The callback is\nperformed before each freeing of an object.\n\nI would think that it is much easier to check the object state manually\nbefore the free. That also places the check near the code object\nmanipulation of the object.\n\nAlso the SLAB_DEBUG_INITIAL callback is only performed if the kernel was\ncompiled with SLAB debugging on. If there would be code in a constructor\nhandling SLAB_DEBUG_INITIAL then it would have to be conditional on\nSLAB_DEBUG otherwise it would just be dead code. But there is no such code\nin the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real\nuse of, difficult to understand and there are easier ways to accomplish the\nsame effect (i.e. add debug code before kfree).\n\nThere is a related flag SLAB_CTOR_VERIFY that is frequently checked to be\nclear in fs inode caches.

The involves some limited recursion.\nThis patch tries to simplify some aspects of this.\n\nAs well as opening the whole device, we need to increment -\u003ebd_part_count when\na partition is opened (this is used by rescan_partitions to avoid a rescan if\nany partition is active, as that would be confusing).\n\nThe main change this patch makes is to move the inc/dec of bd_part_count into\nblkdev_{get,put} for the whole rather than doing it in blkdev_{get,put} for\nthe partition.\n\nMore specifically, we introduce __blkdev_get and __blkdev_put which do exactly\nwhat blkdev_{get,put} did, only with an extra \"for_part\" argument\n(blkget_{get,put} then call the __ version with a \u00270\u0027 for the extra argument).\n\nIf for_part is 1, then the blkdev is being get(put) because a partition is\nbeing opened(closed) for the first(last) time, and so bd_part_count should be\nupdated (on success). The particular advantage of pushing this function down\nis that the bd_mutex lock (which is needed to update bd_part_count) is already\nheld at the lower level.\n\nNote that this slightly changes the semantics of bd_part_count. Instead of\nupdating it whenever a partition is opened or released, it is now only updated\non the first open or last release. This is an adequate semantic as it is only\never tested for \"\u003d\u003d 0\".\n\nHaving introduced these functions we remove the current bd_part_count updates\nfrom do_open (which is really the body of blkdev_get) and call\n__blkdev_get(... 1). Similarly in blkget_put we remove the old bd_part_count\nupdates and call __blkget_put(..., 1). This call is moved to the end of\n__blkdev_put to avoid nested locks of bd_mutex.\n\nFinally the mutex_lock on whole-\u003ebd_mutex in do_open can be removed. It was\nonly really needed to protect bd_part_count, and that is now managed (and\nprotected) within the recursive call.\n\nThe observation that bd_part_count is central to the locking issues, and the\nmodifications to create __blkdev_put are from Peter Zijlstra.\n\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "fd27c7a1bfa9801544ca961cdb4ca0b4998580b8", "tree": "44749ea9d81931cbe5a753b972f6b9fde92a6496", "parents": [ "35a6027f1ab6594068cb8bca7705e4567753946b" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Fri Dec 08 02:36:14 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Fri Dec 08 08:28:38 2006 -0800" }, "message": "[PATCH] lockdep: remove lock_key approach to managing nested bd_mutex locks\n\nThe extra call to get_gendisk is not good.

no lock write handler\n\n__generic_file_aio_write_nolock() - internal worker routine\n\nSigned-off-by: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "ee0b3e671baff681d69fbf0db33b47603c0a8280", "tree": "3202ff815b2196c6c353bc5b28d7a2800df273ec", "parents": [ "027445c37282bc1ed26add45e573ad2d3e4860a5" ], "author": { "name": "Badari Pulavarty", "email": "pbadari@us.ibm.com", "time": "Sat Sep 30 23:28:47 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Oct 01 00:39:28 2006 -0700" }, "message": "[PATCH] Remove readv/writev methods and use aio_read/aio_write instead\n\nThis patch removes readv() and writev() methods and replaces them with\naio_read()/aio_write() methods.\n\nSigned-off-by: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "027445c37282bc1ed26add45e573ad2d3e4860a5", "tree": "93eab101a938ffebaea64703033c8649df4d73f0", "parents": [ "9ea0f9499d15c49df23e7aac4332d830c40e12d0" ], "author": { "name": "Badari Pulavarty", "email": "pbadari@us.ibm.com", "time": "Sat Sep 30 23:28:46 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Oct 01 00:39:28 2006 -0700" }, "message": "[PATCH] Vectorize aio_read/aio_write fileop methods\n\nThis patch vectorizes aio_read() and aio_write() methods to prepare for\ncollapsing all aio \u0026 vectored operations into one interface -

I don\u0027t have a test case for this to happen but it should cause\ndereference of freed pointer.\n\nIf a matching bd_holder is found in bd_holder_list, add_bd_holder() completes\nits job by just incrementing the reference count. In this case, it should be\nconsidered as success but it used to return \u0027fail\u0027 to let the caller free\ntemporary bd_holder. Fixed it to return success and free given object by\nitself.\n\nAlso, if either one of symlinking fails, the bd_holder should not be added to\nthe list so that it can be discarded later.

filesystem operation to take an extra argument that\npermits the VFS to pass in the target vfsmount that defines the mountpoint.\n\nThe filesystem is then required to manually set the superblock and root dentry\npointers. For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing. In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n pointer argument and return an integer, so most filesystems have to change\n very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n normally call simple_set_mnt() to instantiate the vfsmount. This will\n always return 0, and so can be tail-called from get_sb().\n\n (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the\n dcache upon superblock destruction rather than shrink_dcache_anon().\n\n This is required because the superblock may now have multiple trees that\n aren\u0027t actually bound to s_root, but that still need to be cleaned up. The\n currently called functions assume that the whole tree is rooted at s_root,\n and that anonymous dentries are not the roots of trees which results in\n dentries being left unculled.\n\n However, with the way NFS superblock sharing are currently set to be\n implemented, these assumptions are violated: the root of the filesystem is\n simply a dummy dentry and inode (the real inode for \u0027/\u0027 may well be\n inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries\n with child trees.\n\n [*] Anonymous until discovered from another tree.\n\n (*) The documentation has been adjusted, including the additional bit of\n changing ext2_* into foo_* in the documentation.\n\n[akpm@osdl.org: convert ipath_fs, do other stuff]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "09d967c6f32b35eab15b45862ae16e4f06259d8e", "tree": "9fca9dda390612041f857a33cb746fe1eb28b60a", "parents": [ "0e5b3781591cc954037c08ef78edf7f1192d38c5" ], "author": { "name": "OGAWA Hirofumi", "email": "hirofumi@mail.parknet.co.jp", "time": "Thu Jun 22 14:47:21 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Jun 22 15:05:57 2006 -0700" }, "message": "[PATCH] Fix a race condition between -\u003ei_mapping and iput()\n\nThis race became a cause of oops, and can reproduce by the following.\n\n while true; do\n\tdd if\u003d/dev/zero of\u003d/dev/.static/dev/hdg1 bs\u003d512 count\u003d1000 \u0026 sync\n done\n\nThis race condition was between __sync_single_inode() and iput().\n\n cpu0 (fs\u0027s inode) cpu1 (bdev\u0027s inode)\n ----------------- -------------------\n close(\"/dev/hda2\")\n [...]\n__sync_single_inode()\n /* copy the bdev\u0027s -\u003ei_mapping */\n mapping \u003d inode-\u003ei_mapping;\n\n generic_forget_inode()\n bdev_clear_inode()\n\t\t\t\t\t /* restre the fs\u0027s -\u003ei_mapping */\n\t\t\t\t inode-\u003ei_mapping \u003d \u0026inode-\u003ei_data;\n\t\t\t\t /* bdev\u0027s inode was freed */\n destroy_inode(inode);\n\n if (wait) {\n /* dereference a freed bdev\u0027s mapping-\u003ehost */\n filemap_fdatawait(mapping); /* Oops */\n\nSince __sync_single_inode() is only taking a ref-count of fs\u0027s inode, the\nanother process can be close() and freeing the bdev\u0027s inode while writing\nfs\u0027s inode.

I have checked that every user of\ndisk-\u003efops-\u003ecompat_ioctl() in the current git tree gets the BKL itself, so\nit could easily be removed from compat_blkdev_ioctl().\n\nSigned-off-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "2ef41634def0fcb0def3e3c90220c651ca478cb3", "tree": "86fb9c439ad5043d38d69588975e84bd8b565619", "parents": [ "91bb52416854dfd581efe6e2a0aca8dc655f043e" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Thu May 05 16:15:59 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu May 05 16:36:44 2005 -0700" }, "message": "[PATCH] remove do_sync parameter from __invalidate_device\n\nThe only caller that ever sets it can call fsync_bdev itself easily.
