This cleans it up...]\n\nThe attached patch separate jffs2_init_acl() into two parts.\n\nThe one is jffs2_init_acl_pre() called from jffs2_new_inode().\nIt compute ACL oriented inode-\u003ei_mode bits, and allocate in-memory ACL\nobjects associated with the new inode just before when inode meta\ninfomation is written to the medium.\n\nThe other is jffs2_init_acl_post() called from jffs2_symlink(),\njffs2_mkdir(), jffs2_mknod() and jffs2_do_create().\nIt actually writes in-memory ACL objects into the medium next to\nthe success of writing meta-information.\n\nIn the current implementation, we have to write a same inode meta\ninfomation twice when inode-\u003ei_mode is updated by the default ACL.\nHowever, we can avoid the behavior by putting an updated i_mode\nbefore it is written at first, as jffs2_init_acl_pre() doing.\n\nSigned-off-by: KaiGai Kohei \u003ckaigai@ak.jp.nec.com\u003e\nSigned-off-by: David Woodhouse \u003cdwmw2@infradead.org\u003e\n" }, { "commit": "c00046c279a2521075250fad682ca0acc10d4fd7", "tree": "78a7e9089c26f199ad9b0161bb564b7c1ca6daf9", "parents": [ "9abbf7d028b1598b40ebdc81c48f30da7f3d5bf5", "8e8a1407ac23b43cec0412338c1b4f5e1c664550" ], "author": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Oct 19 20:36:17 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Oct 19 20:36:17 2007 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/bunk/trivial\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/bunk/trivial: (74 commits)\n fix do_sys_open() prototype\n sysfs: trivial: fix sysfs_create_file kerneldoc spelling mistake\n Documentation: Fix typo in SubmitChecklist.\n Typo: depricated -\u003e deprecated\n Add missing profile\u003dkvm option to Documentation/kernel-parameters.txt\n fix typo about TBI in e1000 comment\n proc.txt: Add /proc/stat field\n small documentation fixes\n Fix compiler warning in smount example program from sharedsubtree.txt\n docs/sysfs: add missing word to sysfs attribute explanation\n documentation/ext3: grammar fixes\n Documentation/java.txt: typo and grammar fixes\n Documentation/filesystems/vfs.txt: typo fix\n include/asm-*/system.h: remove unused set_rmb(), set_wmb() macros\n trivial copy_data_pages() tidy up\n Fix typo in arch/x86/kernel/tsc_32.c\n file link fix for Pegasus USB net driver help\n remove unused return within void return function\n Typo fixes retrun -\u003e return\n x86 hpet.h: remove broken links\n ...\n" }, { "commit": "b35e7041186a9ace341665d404274d58a32b6e2c", "tree": "68e56db6292bc0853252305345e845620860d995", "parents": [ "5f737085beea3a5c5b6f44a16e6d3e2fd03095e0" ], "author": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Oct 19 19:59:18 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Oct 19 19:59:18 2007 -0700" }, "message": "Avoid compile error in fs/nfs/unlink.c\n\nErez Zadok reports that certain configurations fail to build due to\nschedule() TASK_[UN]INTERRUPTIBLE not being declared.

The proposed\nsolution is treat 64k rec_len with a an impossible value like rec_len \u003d\n0xffff to handle this.\n\nThe Patch-set consists of the following 2 patches.\n [1/2] ext3: enlarge blocksize\n - Allow blocksize up to pagesize\n\n [2/2] ext3: fix rec_len overflow\n - prevent rec_len from overflow with 64KB blocksize\n\nNow on 64k page ppc64 box runs with this patch set we could create a 64k\nblock size ext3, and able to handle empty directory block.\n\nSigned-off-by: Takashi Sato \u003csho@tnes.nec.co.jp\u003e\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nAcked-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "4176ed593866b5e4bcf86896e0734315ad46661b", "tree": "18756b3b0f2ede9925ec8e2ded3652bf76120041", "parents": [ "6bbfb0776615b3cb84ccfec8f5d6214938143b2a" ], "author": { "name": "Andi Drebes", "email": "lists-receive@programmierforen.de", "time": "Thu Oct 18 03:06:55 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Oct 18 14:37:29 2007 -0700" }, "message": "fs/cramfs/inode.c: replace hardcoded value with preprocessor constant\n\nRemove the hardcoded value 256 in fs/cramfs/inode.c and replaces it with\nCRAMFS_MAXPATHLEN.\n\nTested on an i386 box.\nSigned-off-by: Andi Drebes \u003clists-receive@programmierforen.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6bbfb0776615b3cb84ccfec8f5d6214938143b2a", "tree": "00fc93a6097ddd49af32f054216c23d806282592", "parents": [ "b8dc93cbe91324b922395919cd5df4cca2fe55f6" ], "author": { "name": "Andi Drebes", "email": "lists-receive@programmierforen.de", "time": "Thu Oct 18 03:06:54 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Oct 18 14:37:29 2007 -0700" }, "message": "fs/cramfs/inode.c: remove unused variable\n\nRemove a variable that is never read.\n\nSigned-off-by: Andi Drebes \u003clists-receive@programmierforen.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d32c4f2626acc385d5187bd5c0c24f442328dc60", "tree": "cd08c94dcf8610c2c2cfc96e5abe744163f3a038", "parents": [ "188b95dd8ecb02dd6c6e5534cddc5a89aa4e2852" ], "author": { "name": "Jeff Layton", "email": "jlayton@redhat.com", "time": "Thu Oct 18 03:05:22 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Oct 18 14:37:22 2007 -0700" }, "message": "CIFS: ignore mode change if it\u0027s just for clearing setuid/setgid bits\n\nIf the ATTR_KILL_S*ID bits are set then any mode change is only for clearing\nthe setuid/setgid bits.

The VFS will set\nthe ATTR_KILL_SUID or ATTR_KILL_SGID bits in the ia_valid mask, and then call\nnotify_change to clear these bits and set the mode accordingly.\n\nWith a networked filesystem (NFS and CIFS in particular but likely others),\nthe client machine or process may not have credentials that allow for setting\nthe mode. In some situations, this can lead to file corruption, an operation\nfailing outright because the setattr fails, or to races that lead to a mode\nchange being reverted.\n\nIn this situation, we\u0027d like to just leave the handling of this to the server\nand ignore these bits. The problem is that by the time the setattr op is\ncalled, the VFS has already reinterpreted the ATTR_KILL_* bits into a mode\nchange. The setattr operation has no way to know its intent.\n\nThe following patch fixes this by making notify_change no longer clear the\nATTR_KILL_SUID and ATTR_KILL_SGID bits in the ia_valid before handing it off\nto the setattr inode op. setattr can then check for the presence of these\nbits, and if they\u0027re set it can assume that the mode change was only for the\npurposes of clearing these bits.\n\nThis means that we now have an implicit assumption that notify_change is never\ncalled with ATTR_MODE and either ATTR_KILL_S*ID bit set. Nothing currently\nenforces that, so this patch also adds a BUG() if that occurs.\n\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nCc: Michael Halcrow \u003cmhalcrow@us.ibm.com\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Neil Brown \u003cneilb@suse.de\u003e\nCc: \"J.

This is this the most time consuming part\nof the filesystem check. The unintialized block group feature can greatly\nreduce e2fsck time by eliminating checking of uninitialized inodes.\n\nWith this feature, there is a a high water mark of used inodes for each block\ngroup. Block and inode bitmaps can be uninitialized on disk via a flag in the\ngroup descriptor to avoid reading or scanning them at e2fsck time. A checksum\nof each group descriptor is used to ensure that corruption in the group\ndescriptor\u0027s bit flags does not cause incorrect operation.\n\nThe feature is enabled through a mkfs option\n\n\tmke2fs /dev/ -O uninit_groups\n\nA patch adding support for uninitialized block groups to e2fsprogs tools has\nbeen posted to the linux-ext4 mailing list.\n\nThe patches have been stress tested with fsstress and fsx. In performance\ntests testing e2fsck time, we have seen that e2fsck time on ext3 grows\nlinearly with the total number of inodes in the filesytem. In ext4 with the\nuninitialized block groups feature, the e2fsck time is constant, based\nsolely on the number of used inodes rather than the total inode count.\nSince typical ext4 filesystems only use 1-10% of their inodes, this feature can\ngreatly reduce e2fsck time for users. With performance improvement of 2-20\ntimes, depending on how full the filesystem is.\n\nThe attached graph shows the major improvements in e2fsck times in filesystems\nwith a large total inode count, but few inodes in use.\n\nIn each group descriptor if we have\n\nEXT4_BG_INODE_UNINIT set in bg_flags:\n Inode table is not initialized/used in this group. So we can skip\n the consistency check during fsck.\nEXT4_BG_BLOCK_UNINIT set in bg_flags:\n No block in the group is used. So we can skip the block bitmap\n verification for this group.\n\nWe also add two new fields to group descriptor as a part of\nuninitialized group patch.\n\n __le16 bg_itable_unused; /* Unused inodes count */\n __le16 bg_checksum; /* crc16(sb_uuid+group+desc) */\n\nbg_itable_unused:\n\nIf we have EXT4_BG_INODE_UNINIT not set in bg_flags\nthen bg_itable_unused will give the offset within\nthe inode table till the inodes are used. This can be\nused by fsck to skip list of inodes that are marked unused.\n\nbg_checksum:\nNow that we depend on bg_flags and bg_itable_unused to determine\nthe block and inode usage, we need to make sure group descriptor\nis not corrupt. We add checksum to group descriptor to\ndetect corruption. If the descriptor is found to be corrupt, we\nmark all the blocks and inodes in the group used.\n\nSigned-off-by: Avantika Mathur \u003cmathur@us.ibm.com\u003e\nSigned-off-by: Andreas Dilger \u003cadilger@clusterfs.com\u003e\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nSigned-off-by: Aneesh Kumar K.V \u003caneesh.kumar@linux.vnet.ibm.com\u003e\n" }, { "commit": "4074fe3736b1a43431dff870bf9055ac5dcf3f03", "tree": "bd33adb6b06eef7f7405addac686ae170750903d", "parents": [ "f077d0d7ea5d65d01f2ce2e7131e964c13a32433" ], "author": { "name": "Eric Sandeen", "email": "sandeen@redhat.com", "time": "Tue Oct 16 18:38:25 2007 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Oct 17 18:50:00 2007 -0400" }, "message": "ext4: remove #ifdef CONFIG_EXT4_INDEX\n\nCONFIG_EXT4_INDEX is not an exposed config option in the kernel, and it is\nunconditionally defined in ext4_fs.h. tune2fs is already able to turn off\ndir indexing, so at this point it\u0027s just cluttering up the code.
