Instead, we need it to return whether\nthe underlying flash device can have bad eraseblocks or not.  UBI needs\nthis information because it affects how it handles the underlying flash.\nE.g., if the underlying flash is NOR, it cannot have bad blocks and any\nwrite or erase error is fatal, and all we can do is to switch to R/O\nmode.  We do not need to reserve a pool of good eraseblocks for bad\neraseblocks handling, and so on.\n\nThis patch also removes \u0027mtd_can_have_bb()\u0027 invocations from Logfs to\nensure correct Logfs behavior.\n\nI\u0027ve tested that with this patch UBI works on top of NOR and NAND\nflashes emulated by mtdram and nandsim correspondingly.\n\nThis patch is based on patch from Linus Torvalds.\n\nSigned-off-by: Artem Bityutskiy \u003cartem.bityutskiy@linux.intel.com\u003e\nAcked-by: Jörn Engel \u003cjoern@logfs.org\u003e\nAcked-by: Prasad Joshi \u003cprasadjoshi.linux@gmail.com\u003e\nAcked-by: Brian Norris \u003ccomputersforpeace@gmail.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

But that also means that now \"mtd_can_have_bb()\"\nalways returns 0.\n\nNow, \"mtd_block_markbad()\" will obviously return an error if the\nlow-level driver doesn\u0027t support bad blocks, so this is somewhat\nnon-symmetric, but it actually makes sense if a NULL \"block_isbad\"\nfunction is considered to mean \"I assume that all my blocks are always\ngood\".\n"

It keeps track of erase\ncount, level etc. for every segment.\n\nBad things happen with a segment belonging to the segment file is GCed\n\n ------------[ cut here ]------------\nkernel BUG at /home/prasad/logfs/readwrite.c:297!\ninvalid opcode: 0000 [#1] SMP\nModules linked in: logfs joydev usbhid hid psmouse e1000 i2c_piix4\n\t\tserio_raw [last unloaded: logfs]\nPid: 20161, comm: mount Not tainted 3.1.0-rc3+ #3 innotek GmbH\n\t\tVirtualBox\nEIP: 0060:[\u003cf809132a\u003e] EFLAGS: 00010292 CPU: 0\nEIP is at logfs_lock_write_page+0x6a/0x70 [logfs]\nEAX: 00000027 EBX: f73f5b20 ECX: c16007c8 EDX: 00000094\nESI: 00000000 EDI: e59be6e4 EBP: c7337b28 ESP: c7337b18\nDS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068\nProcess mount (pid: 20161, ti\u003dc7336000 task\u003deb323f70 task.ti\u003dc7336000)\nStack:\nf8099a3d c7337b24 f73f5b20 00001002 c7337b50 f8091f6d f8099a4d f80994e4\n00000003 00000000 c7337b68 00000000 c67e4400 00001000 c7337b80 f80935e5\n00000000 00000000 00000000 00000000 e1fcf000 0000000f e59be618 c70bf900\nCall Trace:\n[\u003cf8091f6d\u003e] logfs_get_write_page.clone.16+0xdd/0x100 [logfs]\n[\u003cf80935e5\u003e] logfs_mod_segment_entry+0x55/0x110 [logfs]\n[\u003cf809460d\u003e] logfs_get_segment_entry+0x1d/0x20 [logfs]\n[\u003cf8091060\u003e] ? logfs_cleanup_journal+0x50/0x50 [logfs]\n[\u003cf809521b\u003e] ostore_get_erase_count+0x1b/0x40 [logfs]\n[\u003cf80965b8\u003e] logfs_open_area+0xc8/0x150 [logfs]\n[\u003cc141a7ec\u003e] ? kmemleak_alloc+0x2c/0x60\n[\u003cf809668e\u003e] __logfs_segment_write.clone.16+0x4e/0x1b0 [logfs]\n[\u003cc10dd563\u003e] ? mempool_kmalloc+0x13/0x20\n[\u003cc10dd563\u003e] ? mempool_kmalloc+0x13/0x20\n[\u003cf809696f\u003e] logfs_segment_write+0x17f/0x1d0 [logfs]\n[\u003cf8092e8c\u003e] logfs_write_i0+0x11c/0x180 [logfs]\n[\u003cf8092f35\u003e] logfs_write_direct+0x45/0x90 [logfs]\n[\u003cf80934cd\u003e] __logfs_write_buf+0xbd/0xf0 [logfs]\n[\u003cc102900e\u003e] ? kmap_atomic_prot+0x4e/0xe0\n[\u003cf809424b\u003e] logfs_write_buf+0x3b/0x60 [logfs]\n[\u003cf80947a9\u003e] __logfs_write_inode+0xa9/0x110 [logfs]\n[\u003cf8094cb0\u003e] logfs_rewrite_block+0xc0/0x110 [logfs]\n[\u003cf8095300\u003e] ? get_mapping_page+0x10/0x60 [logfs]\n[\u003cf8095aa0\u003e] ? logfs_load_object_aliases+0x2e0/0x2f0 [logfs]\n[\u003cf808e57d\u003e] logfs_gc_segment+0x2ad/0x310 [logfs]\n[\u003cf808e62a\u003e] __logfs_gc_once+0x4a/0x80 [logfs]\n[\u003cf808ed43\u003e] logfs_gc_pass+0x683/0x6a0 [logfs]\n[\u003cf8097a89\u003e] logfs_mount+0x5a9/0x680 [logfs]\n[\u003cc1126b21\u003e] mount_fs+0x21/0xd0\n[\u003cc10f6f6f\u003e] ? __alloc_percpu+0xf/0x20\n[\u003cc113da41\u003e] ? alloc_vfsmnt+0xb1/0x130\n[\u003cc113db4b\u003e] vfs_kern_mount+0x4b/0xa0\n[\u003cc113e06e\u003e] do_kern_mount+0x3e/0xe0\n[\u003cc113f60d\u003e] do_mount+0x34d/0x670\n[\u003cc10f2749\u003e] ? strndup_user+0x49/0x70\n[\u003cc113fcab\u003e] sys_mount+0x6b/0xa0\n[\u003cc142d87c\u003e] syscall_call+0x7/0xb\nCode: f8 e8 8b 93 39 c9 8b 45 f8 3e 0f ba 28 00 19 d2 85 d2 74 ca eb d0 0f 0b 8d 45 fc 89 44 24 04 c7 04 24 3d 9a 09 f8 e8 09 92 39 c9 \u003c0f\u003e 0b 8d 74 26 00 55 89 e5 3e 8d 74 26 00 8b 10 80 e6 01 74 09\nEIP: [\u003cf809132a\u003e] logfs_lock_write_page+0x6a/0x70 [logfs] SS:ESP 0068:c7337b18\n---[ end trace 96e67d5b3aa3d6ca ]---\n\nThe patch passes locked page to __logfs_write_inode.

We need this because\nwe want to add common code to to all drivers in the mtd core level,\nwhich is impossible with the current interface when MTD clients\ncall driver functions like \u0027read()\u0027 or \u0027write()\u0027 directly.\n\nAt this point we just introduce a new inline wrapper function, but\nlater some of them are expected to gain more code. E.g., the input\nparameters check should be moved to the wrappers rather than be\nduplicated at many drivers.\n\nThis particular patch introduced the \u0027mtd_erase()\u0027 interface.

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"

Reorganize the interface such that,\n\n* blkdev_get() is extended to include exclusive access management.\n  @holder argument is added and, if is @FMODE_EXCL specified, it will\n  gain exclusive access atomically w.r.t. other exclusive accesses.\n\n* blkdev_put() is similarly extended.  It now takes @mode argument and\n  if @FMODE_EXCL is set, it releases an exclusive access.  Also, when\n  the last exclusive claim is released, the holder/slave symlinks are\n  removed automatically.\n\n* bd_claim/release() and close_bdev_exclusive() are no longer\n  necessary and either made static or removed.\n\n* bd_link_disk_holder() remains the same but bd_unlink_disk_holder()\n  is no longer necessary and removed.\n\n* open_bdev_exclusive() becomes a simple wrapper around lookup_bdev()\n  and blkdev_get().  It also has an unexpected extra bdev_read_only()\n  test which probably should be moved into blkdev_get().\n\n* open_by_devnum() is modified to take @holder argument and pass it to\n  blkdev_get().\n\nMost of bdev open/close operations are unified into blkdev_get/put()\nand most exclusive accesses are tested atomically at the open time (as\nit should).  This cleans up code and removes some, both valid and\ninvalid, but unnecessary all the same, corner cases.\n\nopen_bdev_exclusive() and open_by_devnum() can use further cleanup -\nrename to blkdev_get_by_path() and blkdev_get_by_devt() and drop\nspecial features.

      "message": "llseek: automatically add .llseek fop\n\nAll file_operations should get a .llseek operation so we can make\nnonseekable_open the default for future file operations without a\n.llseek pointer.\n\nThe three cases that we can automatically detect are no_llseek, seq_lseek\nand default_llseek. For cases where we can we can automatically prove that\nthe file offset is always ignored, we use noop_llseek, which maintains\nthe current behavior of not returning an error from a seek.\n\nNew drivers should normally not use noop_llseek but instead use no_llseek\nand call nonseekable_open at open time.  Existing drivers can be converted\nto do the same when the maintainer knows for certain that no user code\nrelies on calling seek on the device file.\n\nThe generated code is often incorrectly indented and right now contains\ncomments that clarify for each added line why a specific variant was\nchosen. In the version that gets submitted upstream, the comments will\nbe gone and I will manually fix the indentation, because there does not\nseem to be a way to do that using coccinelle.\n\nSome amount of new code is currently sitting in linux-next that should get\nthe same modifications, which I will do at the end of the merge window.\n\nMany thanks to Julia Lawall for helping me learn to write a semantic\npatch that does all this.\n\n\u003d\u003d\u003d\u003d\u003d begin semantic patch \u003d\u003d\u003d\u003d\u003d\n// This adds an llseek\u003d method to all file operations,\n// as a
