But\nit is not enough because simple_write_end() does not call\nmark_inode_dirty() when it extends i_size. So even if we do\ncall mark_inode_dirty at beginning of write out, with a very\nlong IO and a saturated system we might get the .write_inode()\ncalled while still extend-writing to file and miss out on the last\ni_size updates.\n\nSo override .write_end, call simple_write_end(), and afterwords if\ni_size was changed call mark_inode_dirty().\n\nIt stands to logic that since simple_write_end() was the one extending\ni_size it should also call mark_inode_dirty(). But it looks like all\nusers of simple_write_end() are memory-bound pseudo filesystems, who\ncould careless about mark_inode_dirty(). I might submit a\nwarning-comment patch to simple_write_end() in future.\n\nCC: Stable \u003cstable@kernel.org\u003e\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"

      "message": "block: add rq-\u003eresid_len\n\nrq-\u003edata_len served two purposes - the length of data buffer on issue\nand the residual count on completion.  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.
