      "message": "fs: icache RCU free inodes\n\nRCU free the struct inode. This will allow:\n\n- Subsequent store-free path walking patch. The inode must be consulted for\n  permissions when walking, so an RCU inode reference is a must.\n- sb_inode_list_lock to be moved inside i_lock because sb list walkers who want\n  to take i_lock no longer need to take sb_inode_list_lock to walk the list in\n  the first place. This will simplify and optimize locking.\n- Could remove some nested trylock loops in dcache code\n- Could potentially simplify things a bit in VM land. Do not need to take the\n  page lock to follow page-\u003emapping.\n\nThe downsides of this is the performance cost of using RCU. In a simple\ncreat/unlink microbenchmark, performance drops by about 10% due to inability to\nreuse cache-hot slab objects. As iterations increase and RCU freeing starts\nkicking over, this increases to about 20%.\n\nIn cases where inode lifetimes are longer (ie. many inodes may be allocated\nduring the average life span of a single inode), a lot of this cache reuse is\nnot applicable, so the regression caused by this patch is smaller.\n\nThe cache-hot regression could largely be avoided by using SLAB_DESTROY_BY_RCU,\nhowever this adds some complexity to list walking and store-free path walking,\nso I prefer to implement this at a later date, if it is shown to be a win in\nreal situations. I haven\u0027t found a regression in any non-micro benchmark so I\ndoubt it will be a problem.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n"

      "message": "include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h\n\npercpu.h is included by sched.h and module.h and thus ends up being\nincluded when building most .c files.  percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed.  Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability.  As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n  http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n  only the necessary includes are there.  ie. if only gfp is used,\n  gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n  blocks and try to put the new include such that its order conforms\n  to its surrounding.  It\u0027s put in the include block which contains\n  core kernel includes, in the same order that the rest are ordered -\n  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n  doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n  because the file doesn\u0027t have fitting include block), it prints out\n  an error message indicating which .h file needs to be added to the\n  file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n   over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n   and ~3000 slab.h inclusions.  The script emitted errors for ~400\n   files.\n\n2. Each error was manually checked.  Some didn\u0027t need the inclusion,\n   some needed manual addition while adding it to implementation .h or\n   embedding .c file was more appropriate for others.  This step added\n   inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n   from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n   e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n   APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n   editing them as sprinkling gfp.h and slab.h inclusions around .h\n   files could easily lead to inclusion dependency hell.  Most gfp.h\n   inclusion directives were ignored as stuff from gfp.h was usually\n   wildly available and often used in preprocessor macros.  Each\n   slab.h inclusion directive was examined and added manually as\n   necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my\n   distributed build env didn\u0027t work with gcov compiles) and a few\n   more options had to be turned off depending on archs to make things\n   build (like ipr on powerpc/64 which failed due to missing writeq).\n\n   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n   * powerpc and powerpc64 SMP allmodconfig\n   * sparc and sparc64 SMP allmodconfig\n   * ia64 SMP allmodconfig\n   * s390 SMP allmodconfig\n   * alpha SMP allmodconfig\n   * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n   a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n"

Including variable sized\nstripe_unit.\n\nSome limits:\n* stripe_unit must be a multiple of PAGE_SIZE\n* stripe_unit * stripe_count is maximum upto 32-bit (4Gb)\n\nTested RAID0 over mirrors, RAID0 only, mirrors only. All check.\n\nDesign notes:\n* I\u0027m not using a vectored raid-engine mechanism yet. Following the\n  pnfs-objects-layout data-map structure, \"Mirror\" is just a private\n  case of \"group_width\" \u003d\u003d 1, and RAID0 is a private case of\n  \"Mirrors\" \u003d\u003d 1. The performance lose of the general case over the\n  particular special case optimization is totally negligible, also\n  considering the extra code size.\n\n* In general I added a prepare_stripes() stage that divides the\n  to-be-io pages to the participating devices, the previous\n  exofs_ios_write/read, now becomes _write/read_mirrors and a new\n  write/read upper layer loops on all devices calling\n  _write/read_mirrors. Effectively the prepare_stripes stage is the all\n  secret.\n  Also truncate need fixing to accommodate for striping.\n\n* In a RAID0 arrangement, in a regular usage scenario, if all inode\n  layouts will start at the same device, the small files fill up the\n  first device and the later devices stay empty, the farther the device\n  the emptier it is.\n\n  To fix that, each inode will start at a different stripe_unit,\n  according to it\u0027s obj_id modulus number-of-stripe-units. And\n  will then span all stripe-units in the same incrementing order\n  wrapping back to the beginning of the device table. We call it\n  a stripe-units moving window.\n\n  Special consideration was taken to keep all devices in a mirror\n  arrangement identical. So a broken osd-device could just be cloned\n  from one of the mirrors and no FS scrubbing is needed. (We do that\n  by rotating stripe-unit at a time and not a single device at a time.)\n\nTODO:\n We no longer verify object_length \u003d\u003d inode-\u003ei_size in exofs_iget.\n (since i_size is stripped on multiple objects now).\n I should introduce a multiple-device attribute reading, and use\n it in exofs_iget.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\n"

      "message": "exofs: fix pnfs_osd re-definitions in pre-pnfs trees\n\nSome on disk exofs constants and types are defined in the pnfs_osd_xdr.h\nfile. Since we needed these types before the pnfs-objects code was\naccepted to mainline we duplicated the minimal needed definitions into\nan exofs local header. The definitions where conditionally included\ndepending on !CONFIG_PNFS defined. So if PNFS was present in the tree\ndefinitions are taken from there and if not they are defined locally.\n\nThat was all good but, the CONFIG_PNFS is planed to be included upstream\nbefore the pnfs-objects is also included. (The first pnfs batch might be\npnfs-files only)\n\nSo condition exofs local definitions on the absence of pnfs_osd_xdr.h\ninclusion (__PNFS_OSD_XDR_H__ not defined). User code must make sure\nthat in future pnfs_osd_xdr.h will be included before fs/exofs/pnfs.h,\nwhich happens to be so in current code.\n\nOnce pnfs-objects hits mainline, exofs\u0027s local header will be removed.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\n"

      "message": "exofs: Multi-device mirror support\n\nThis patch changes on-disk format, it is accompanied with a parallel\npatch to mkfs.exofs that enables multi-device capabilities.\n\nAfter this patch, old exofs will refuse to mount a new formatted FS and\nnew exofs will refuse an old format. This is done by moving the magic\nfield offset inside the FSCB. A new FSCB *version* field was added. In\nthe future, exofs will refuse to mount unmatched FSCB version. To\nup-grade or down-grade an exofs one must use mkfs.exofs --upgrade option\nbefore mounting.\n\nIntroduced, a new object that contains a *device-table*. This object\ncontains the default *data-map* and a linear array of devices\ninformation, which identifies the devices used in the filesystem. This\nobject is only written to offline by mkfs.exofs. This is why it is kept\nseparate from the FSCB, since the later is written to while mounted.\n\nSame partition number, same object number is used on all devices only\nthe device varies.\n\n* define the new format, then load the device table on mount time make\n  sure every thing is supported.\n\n* Change I/O engine to now support Mirror IO, .i.e write same data\n  to multiple devices, read from a random device to spread the\n  read-load from multiple clients (TODO: stripe read)\n\nImplementation notes:\n A few points introduced in previous patch should be mentioned here:\n\n* Special care was made so absolutlly all operation that have any chance\n  of failing are done before any osd-request is executed. This is to\n  minimize the need for a data consistency recovery, to only real IO\n  errors.\n\n* Each IO state has a kref. It starts at 1, any osd-request executed\n  will increment the kref, finally when all are executed the first ref\n  is dropped. At IO-done, each request completion decrements the kref,\n  the last one to return executes the internal _last_io() routine.\n  _last_io() will call the registered io_state_done. On sync mode a\n  caller does not supply a done method, indicating a synchronous\n  request, the caller is put to sleep and a special io_state_done is\n  registered that will awaken the caller. Though also in sync mode all\n  operations are executed in parallel.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\n"

Currently only one device is used but later\nwhen adding more devices, we will drive all devices in parallel according\nto a \"data_map\" that describes how data is arranged on multiple devices.\nThe file system level operates, like before, as if there is one object\n(inode-number) and an i_size. The io engine will split this to the same\nobject-number but on multiple device.\n\nAt first we introduce Mirror (raid 1) layout.

This duality creates some\nheadaches.\n\nFirst of all, block layer and low level drivers can\u0027t really determine\nwhat rq-\u003edata_len contains while a request is executing.  It could be\nthe total request length or it coulde be anything else one of the\nlower layers is using to keep track of residual count.  This\ncomplicates things because blk_rq_bytes() and thus\n[__]blk_end_request_all() relies on rq-\u003edata_len for PC commands.\nDrivers which want to report residual count should first cache the\ntotal request length, update rq-\u003edata_len and then complete the\nrequest with the cached data length.\n\nSecondly, it makes requests default to reporting full residual count,\nie. reporting that no data transfer occurred.  The residual count is\nan exception not the norm; however, the driver should clear\nrq-\u003edata_len to zero to signify the normal cases while leaving it\nalone means no data transfer occurred at all.  This reverse default\nbehavior complicates code unnecessarily and renders block PC on some\ndrivers (ide-tape/floppy) unuseable.\n\nThis patch adds rq-\u003eresid_len which is used only for residual count.\n\nWhile at it, remove now unnecessasry blk_rq_bytes() caching in\nide_pc_intr() as rq-\u003edata_len is not changed anymore.\n\nBoaz\t: spotted missing conversion in osd\nSergei\t: spotted too early conversion to blk_rq_bytes() in ide-tape\n\n[ Impact: cleanup residual count handling, report 0 resid by default ]\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nCc: Bartlomiej Zolnierkiewicz \u003cbzolnier@gmail.com\u003e\nCc: Borislav Petkov \u003cpetkovbb@googlemail.com\u003e\nCc: Sergei Shtylyov \u003csshtylyov@ru.mvista.com\u003e\nCc: Mike Miller \u003cmike.miller@hp.com\u003e\nCc: Eric Moore \u003cEric.Moore@lsi.com\u003e\nCc: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nCc: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Doug Gilbert \u003cdgilbert@interlog.com\u003e\nCc: Mike Miller \u003cmike.miller@hp.com\u003e\nCc: Eric Moore \u003cEric.Moore@lsi.com\u003e\nCc: Darrick J.

This applies to both regular files and other\n  types (directories, device files, symlinks, etc.).\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\n"
