So, we cannot take a backup which keeps the\nfilesystem\u0027s consistency with the storage device\u0027s features (snapshot and\nreplication) while it is mounted.\n\nIn many case, a commercial filesystem (e.g. VxFS) has the freeze feature\nand it would be used to get the consistent backup.\n\nIf Linux\u0027s standard filesystem ext3 has the freeze feature, we can do it\nwithout a commercial filesystem.\n\nSo I have implemented the ioctls of the freeze feature.\nI think we can take the consistent backup with the following steps.\n1. Freeze the filesystem with the freeze ioctl.\n2. Separate the replication volume or create the snapshot\n with the storage device\u0027s feature.\n3. Unfreeze the filesystem with the unfreeze ioctl.\n4. Take the backup from the separated replication volume\n or the snapshot.\n\nThis patch:\n\nVFS:\nChanged the type of write_super_lockfs and unlockfs from \"void\"\nto \"int\" so that they can return an error.\nRename write_super_lockfs and unlockfs of the super block operation\nfreeze_fs and unfreeze_fs to avoid a confusion.\n\next3, ext4, xfs, gfs2, jfs:\nChanged the type of write_super_lockfs and unlockfs from \"void\"\nto \"int\" so that write_super_lockfs returns an error if needed,\nand unlockfs always returns 0.\n\nreiserfs:\nChanged the type of write_super_lockfs and unlockfs from \"void\"\nto \"int\" so that they always return 0 (success) to keep a current behavior.\n\nSigned-off-by: Takashi Sato \u003ct-sato@yk.jp.nec.com\u003e\nSigned-off-by: Masayuki Hamaguchi \u003cm-hamaguchi@ys.jp.nec.com\u003e\nCc: \u003cxfs-masters@oss.sgi.com\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Dave Kleikamp \u003cshaggy@austin.ibm.com\u003e\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nCc: Alasdair G Kergon \u003cagk@redhat.com\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "2150edc6c5cf00f7adb54538b9ea2a3e9cedca3f", "tree": "f72a0d85e66f500b4cead348a231e3d3b9f357bc", "parents": [ "cd764695b67386a81964f68e9c66efd9f13f4d29", "4b905671d2ea09fd48fed72c581df17e40823f39" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 08 17:14:59 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 08 17:14:59 2009 -0800" }, "message": "Merge branch \u0027for_linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4\n\n* \u0027for_linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (57 commits)\n jbd2: Fix oops in jbd2_journal_init_inode() on corrupted fs\n ext4: Remove \"extents\" mount option\n block: Add Kconfig help which notes that ext4 needs CONFIG_LBD\n ext4: Make printk\u0027s consistently prefixed with \"EXT4-fs: \"\n ext4: Add sanity checks for the superblock before mounting the filesystem\n ext4: Add mount option to set kjournald\u0027s I/O priority\n jbd2: Submit writes to the journal using WRITE_SYNC\n jbd2: Add pid and journal device name to the \"kjournald2 starting\" message\n ext4: Add markers for better debuggability\n ext4: Remove code to create the journal inode\n ext4: provide function to release metadata pages under memory pressure\n ext3: provide function to release metadata pages under memory pressure\n add releasepage hooks to block devices which can be used by file systems\n ext4: Fix s_dirty_blocks_counter if block allocation failed with nodelalloc\n ext4: Init the complete page while building buddy cache\n ext4: Don\u0027t allow new groups to be added during block allocation\n ext4: mark the blocks/inode bitmap beyond end of group as used\n ext4: Use new buffer_head flag to check uninit group bitmaps initialization\n ext4: Fix the race between read_inode_bitmap() and ext4_new_inode()\n ext4: code cleanup\n ...\n" }, { "commit": "73ac36ea14fd18ea3dc057e41b16ff31a3c0bd5a", "tree": "7f187cade83d9ca9bd180273c25e1216a1dff506", "parents": [ "da2bdf9a6ff40b10d77620d0d76b02a738c103cb" ], "author": { "name": "Coly Li", "email": "coyli@suse.de", "time": "Wed Jan 07 18:09:16 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 08 08:31:15 2009 -0800" }, "message": "fix similar typos to successfull\n\nWhen I review ocfs2 code, find there are 2 typos to \"successfull\".

It zeroes out counters on \"other\" cpus,\nwithout holding any locks which will prevent races agaist updates from\nthose other CPUS.\n\nThis patch reverts 1f7c14c62ce63805f9574664a6c6de3633d4a354. This means\nthat percpu_counter_sum_and_set() still has the race, but\npercpu_counter_sum() does not.\n\nNote that this is not a simple revert - ext4 has since started using\npercpu_counter_sum() for its dirty_blocks counter as well.\n\nNote that this revert patch changes percpu_counter_sum() semantics.\n\nBefore the patch, a call to percpu_counter_sum() will bring the counter\u0027s\ncentral counter mostly up-to-date, so a following percpu_counter_read()\nwill return a close value.\n\nAfter this patch, a call to percpu_counter_sum() will leave the counter\u0027s\ncentral accumulator unaltered, so a subsequent call to\npercpu_counter_read() can now return a significantly inaccurate result.\n\nIf there is any code in the tree which was introduced after\ne8ced39d5e8911c662d4d69a342b9d053eaaac4e was merged, and which depends\nupon the new percpu_counter_sum() semantics, that code will break.\n\nReported-by: Eric Dumazet \u003cdada1@cosmosbay.com\u003e\nCc: \"David S.

The root cause of this bug was the fact that if\nan uninitalized bitmap block gets read in by userspace (which\ne2fsprogs does try to avoid, but can happen when the blocksize is less\nthan the pagesize and an adjacent blocks is read into memory)\next4_read_block_bitmap() was erroneously depending on the buffer\nuptodate flag to decide whether it needed to initialize the bitmap\nblock in memory --- i.e., to set the standard set of blocks in use by\na block group (superblock, bitmaps, inode table, etc.). Essentially,\next4_read_block_bitmap() assumed it was the only routine that might\ntry to read a block containing a block bitmap, which is simply not\ntrue. \n\nTo fix this, ext4_read_block_bitmap() and ext4_read_inode_bitmap()\nmust always initialize uninitialized bitmap blocks.
