The fact that parts of the inode table are\nuninitialized is not a problem so long as the block group descriptors,\nwhich contain information regarding how much of the inode table has\nbeen initialized, has not been corrupted However, if the block group\nchecksums are not valid, e2fsck must scan the entire inode table, and\nthe the old, uninitialized data could potentially cause e2fsck to\nreport false problems.\n\nHence, it is important for the inode tables to be initialized as soon\nas possble. This commit adds this feature so that mke2fs can safely\nuse the lazy inode table initialization feature to speed up formatting\nfile systems.\n\nThis is done via a new new kernel thread called ext4lazyinit, which is\ncreated on demand and destroyed, when it is no longer needed. There\nis only one thread for all ext4 filesystems in the system. When the\nfirst filesystem with inititable mount option is mounted, ext4lazyinit\nthread is created, then the filesystem can register its request in the\nrequest list.\n\nThis thread then walks through the list of requests picking up\nscheduled requests and invoking ext4_init_inode_table(). Next schedule\ntime for the request is computed by multiplying the time it took to\nzero out last inode table with wait multiplier, which can be set with\nthe (init_itable\u003dn) mount option (default is 10). We are doing\nthis so we do not take the whole I/O bandwidth. When the thread is no\nlonger necessary (request list is empty) it frees the appropriate\nstructures and exits (and can be created later later by another\nfilesystem).\n\nWe do not disturb regular inode allocations in any way, it just do not\ncare whether the inode table is, or is not zeroed. But when zeroing, we\nhave to skip used inodes, obviously. Also we should prevent new inode\nallocations from the group, while zeroing is on the way. For that we\ntake write alloc_sem lock in ext4_init_inode_table() and read alloc_sem\nin the ext4_claim_inode, so when we are unlucky and allocator hits the\ngroup which is currently being zeroed, it just has to wait.\n\nThis can be suppresed using the mount option no_init_itable.\n\nSigned-off-by: Lukas Czerner \u003clczerner@redhat.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "5f248c9c251c60af3403902b26e08de43964ea0b", "tree": "6d3328e72a7e4015a64017eb30be18095c6a3c64", "parents": [ "f6cec0ae58c17522a7bc4e2f39dae19f199ab534", "dca332528bc69e05f67161e1ed59929633d5e63d" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Aug 10 11:26:52 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Aug 10 11:26:52 2010 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6: (96 commits)\n no need for list_for_each_entry_safe()/resetting with superblock list\n Fix sget() race with failing mount\n vfs: don\u0027t hold s_umount over close_bdev_exclusive() call\n sysv: do not mark superblock dirty on remount\n sysv: do not mark superblock dirty on mount\n btrfs: remove junk sb_dirt change\n BFS: clean up the superblock usage\n AFFS: wait for sb synchronization when needed\n AFFS: clean up dirty flag usage\n cifs: truncate fallout\n mbcache: fix shrinker function return value\n mbcache: Remove unused features\n add f_flags to struct statfs(64)\n pass a struct path to vfs_statfs\n update VFS documentation for method changes.\n All filesystems that need invalidate_inode_buffers() are doing that explicitly\n convert remaining -\u003eclear_inode() to -\u003eevict_inode()\n Make -\u003edrop_inode() just return whether inode needs to be dropped\n fs/inode.c:clear_inode() is gone\n fs/inode.c:evict() doesn\u0027t care about delete vs. non-delete paths now\n ...\n\nFix up trivial conflicts in fs/nilfs2/super.c\n" }, { "commit": "0930fcc1ee2f0a810b938bc283a3a262d7adccbb", "tree": "5e5d10894f1e31a7aede75110b43d7a41347631d", "parents": [ "7da08fd17a6e42d80f0f3897a5cbd682e77bcdb4" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Mon Jun 07 13:16:22 2010 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Mon Aug 09 16:48:30 2010 -0400" }, "message": "convert ext4 to -\u003eevict_inode()\n\npretty much brute-force...\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "a0375156ca1041574b5d47cc7e32f10b891151b0", "tree": "b791961012b9348f289c3dda5dc071bdf9b736d2", "parents": [ "7e27d6e778cd87b6f2415515d7127eba53fe5d02" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Fri Jun 11 23:14:04 2010 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Fri Jun 11 23:14:04 2010 -0400" }, "message": "ext4: Clean up s_dirt handling\n\nWe don\u0027t need to set s_dirt in most of the ext4 code when journaling\nis enabled.

There are a few exceptions, most\nnotably when resizing the file system, where the superblock needs to\nbe modified --- and in that case it should be done as a journalled\noperation if possible, and s_dirt set only in no-journal mode.\n\nThis patch will optimize out some unneeded disk writes when using ext4\nwith a journal.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "e4ce30f3779c2ddaa7dfaa4042209e5dbacbada5", "tree": "cc64c1dcd16b5dbf71ebc8338b339e6fb04abaee", "parents": [ "b899ebeb05da4287ce845976727e3e83dadd25d5", "14ece1028b3ed53ffec1b1213ffc6acaf79ad77c" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 27 10:26:37 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 27 10:26:37 2010 -0700" }, "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: (40 commits)\n ext4: Make fsync sync new parent directories in no-journal mode\n ext4: Drop whitespace at end of lines\n ext4: Fix compat EXT4_IOC_ADD_GROUP\n ext4: Conditionally define compat ioctl numbers\n tracing: Convert more ext4 events to DEFINE_EVENT\n ext4: Add new tracepoints to track mballoc\u0027s buddy bitmap loads\n ext4: Add a missing trace hook\n ext4: restart ext4_ext_remove_space() after transaction restart\n ext4: Clear the EXT4_EOFBLOCKS_FL flag only when warranted\n ext4: Avoid crashing on NULL ptr dereference on a filesystem error\n ext4: Use bitops to read/modify i_flags in struct ext4_inode_info\n ext4: Convert calls of ext4_error() to EXT4_ERROR_INODE()\n ext4: Convert callers of ext4_get_blocks() to use ext4_map_blocks()\n ext4: Add new abstraction ext4_map_blocks() underneath ext4_get_blocks()\n ext4: Use our own write_cache_pages()\n ext4: Show journal_checksum option\n ext4: Fix for ext4_mb_collect_stats()\n ext4: check for a good block group before loading buddy pages\n ext4: Prevent creation of files larger than RLIMIT_FSIZE using fallocate\n ext4: Remove extraneous newlines in ext4_msg() calls\n ...\n\nFixed up trivial conflict in fs/ext4/fsync.c\n" }, { "commit": "b10b8520903204c9a1e4ef4a6827c2f1569aae9b", "tree": "49b78527451cf32cfc16be194261308b8c27a6be", "parents": [ "aab99c2c26f74d90f615fcca534172dfc1c8bec2" ], "author": { "name": "Dmitry Monakhov", "email": "dmonakhov@openvz.org", "time": "Thu Mar 04 17:31:51 2010 +0300" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Fri May 21 18:31:24 2010 -0400" }, "message": "ext4: replace inode uid,gid,mode init with helper\n\nSigned-off-by: Dmitry Monakhov \u003cdmonakhov@openvz.org\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "12e9b892002d9af057655d35b44db8ee9243b0dc", "tree": "c5831b4bcf98eebdd39158d08dab97c198f5c683", "parents": [ "24676da469f50f433baa347845639662c561d1f6" ], "author": { "name": "Dmitry Monakhov", "email": "dmonakhov@openvz.org", "time": "Sun May 16 22:00:00 2010 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sun May 16 22:00:00 2010 -0400" }, "message": "ext4: Use bitops to read/modify i_flags in struct ext4_inode_info\n\nAt several places we modify EXT4_I(inode)-\u003ei_flags without holding\ni_mutex (ext4_do_update_inode, ...).

Once a block or\ninode is allocated out of that bitmap, it will be marked as\ninitialized in the block group descriptor, so in general this won\u0027t\nresult any extra unnecessary work.\n\nSigned-off-by: Frederic Bohe \u003cfrederic.bohe@bull.net\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "c2ea3fde61f1df1dbf062345f23277dcd6f01dfe", "tree": "53ecbf57416326810540494e814c05753bf30874", "parents": [ "240799cdf22bd789ea6852653c3b879d35ad0a6c" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Fri Oct 10 09:40:52 2008 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Fri Oct 10 09:40:52 2008 -0400" }, "message": "ext4: Remove old legacy block allocator\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "af5bc92dded4d98dfeabc8b5b9812571345b263d", "tree": "5cfaf27e673a09d3ad1341c175559be0a3ea990d", "parents": [ "e5f8eab8851dff162e7ade46f084cb8575dc45f7" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Sep 08 22:25:24 2008 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Sep 08 22:25:24 2008 -0400" }, "message": "ext4: Fix whitespace checkpatch warnings/errors\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n\n" }, { "commit": "4776004f54e4190e104caf620fd0fa5909412236", "tree": "ebd37cb847d58d434ad4ea3bd98c77256f05347e", "parents": [ "1f7c14c62ce63805f9574664a6c6de3633d4a354" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Sep 08 23:00:52 2008 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Sep 08 23:00:52 2008 -0400" }, "message": "ext4: Add printk priority levels to clean up checkpatch warnings\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n\n" }, { "commit": "c001077f4003fa75793bb62979baa6241dd8eb19", "tree": "74d37ab68e3cfe514b8a46bd8324ba713bdc605f", "parents": [ "37609fd5ae62db75026d9f53096a1fbc35e040d9" ], "author": { "name": "Eric Sandeen", "email": "sandeen@redhat.com", "time": "Tue Aug 19 22:19:50 2008 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Tue Aug 19 22:19:50 2008 -0400" }, "message": "ext4: Fix bug where we return ENOSPC even though we have plenty of inodes\n\nThe find_group_flex() function starts with best_flex as the\nparent_fbg_group, which happens to have 0 inodes free.
