If the inode is being freed then\nwhen we try to igrab the inode, we end up tripping the BUG_ON at\nfs/ext4/page-io.c:146.\n\nTo solve this problem, we need to keep track of the number of io\ncallbacks which are pending, and avoid destroying the inode until they\nhave all been completed.

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": "a1c6c5698d53db4c47a25c3a8d11731a4d7b8370", "tree": "4c0b46a74ea1699f8a5e2765a432fec35fb38bcb", "parents": [ "53fdcf992d616484d388a8ab9dad07dc8b8f1178" ], "author": { "name": "Sergey Senozhatsky", "email": "sergey.senozhatsky@gmail.com", "time": "Wed Oct 27 21:30:04 2010 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Oct 27 21:30:04 2010 -0400" }, "message": "ext4: fix NULL pointer dereference in print_daily_error_info()\n\nFix NULL pointer dereference in print_daily_error_info, when \ncalled on unmounted fs (EXT4_SB(sb) returns NULL), by removing error \nreporting timer in ext4_put_super.\n\nGoogle-Bug-Id: 3017663\n\nSigned-off-by: Sergey Senozhatsky \u003csergey.senozhatsky@gmail.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "79f14b7c56d3b3ba58f8b43d1f70b9b71477a800", "tree": "3bb53b7806c1baba6cc24b91724a9264cceccd39", "parents": [ "c37927d4359e81b85de644f8fb08878717cf5f3f", "6d7bccc2215c37205ede6c9cf84db64e7c4f9443" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Oct 22 10:52:01 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Oct 22 10:52:01 2010 -0700" }, "message": "Merge branch \u0027vfs\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/bkl\n\n* \u0027vfs\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/bkl: (30 commits)\n BKL: remove BKL from freevxfs\n BKL: remove BKL from qnx4\n autofs4: Only declare function when CONFIG_COMPAT is defined\n autofs: Only declare function when CONFIG_COMPAT is defined\n ncpfs: Lock socket in ncpfs while setting its callbacks\n fs/locks.c: prepare for BKL removal\n BKL: Remove BKL from ncpfs\n BKL: Remove BKL from OCFS2\n BKL: Remove BKL from squashfs\n BKL: Remove BKL from jffs2\n BKL: Remove BKL from ecryptfs\n BKL: Remove BKL from afs\n BKL: Remove BKL from USB gadgetfs\n BKL: Remove BKL from autofs4\n BKL: Remove BKL from isofs\n BKL: Remove BKL from fat\n BKL: Remove BKL from ext2 filesystem\n BKL: Remove BKL from do_new_mount()\n BKL: Remove BKL from cgroup\n BKL: Remove BKL from NTFS\n ...\n" }, { "commit": "f2143c4e2ebc6be3f07b7c7527dae7313fde23e1", "tree": "5911d66d2c443d66e20639f0ff9f6c4830384245", "parents": [ "77b54a46a83232d172d55013c3af838190615260" ], "author": { "name": "Jan Blunck", "email": "jblunck@infradead.org", "time": "Wed Feb 24 13:25:30 2010 +0100" }, "committer": { "name": "Arnd Bergmann", "email": "arnd@arndb.de", "time": "Mon Oct 04 21:10:38 2010 +0200" }, "message": "BKL: Remove BKL from ext4 filesystem\n\nThe BKL is still used in ext4_put_super(), ext4_fill_super() and\next4_remount().

This didn\u0027t matter as much\nwhen functions which managed the reserved metadata blocks were more\naggressive about dropping reserved metadata blocks as delayed\nallocation blocks were written, but unfortunately they were too\naggressive. This was fixed in commit 0637c6f, but as a result the\nover-estimation by ext4_calc_metadata_amount() would lead to reserving\n2-3 times the number of pending delayed allocation blocks as\npotentially required metadata blocks. So if there are 1 megabytes of\nblocks which have been not yet been allocation, up to 3 megabytes of\nspace would get reserved out of the user\u0027s quota and from the file\nsystem free space pool until all of the inode\u0027s data blocks have been\nallocated.\n\nThis commit addresses this problem by much more accurately estimating\nthe number of metadata blocks that will be required. It will still\nsomewhat over-estimate the number of blocks needed, since it must make\na worst case estimate not knowing which physical blocks will be\nneeded, but it is much more accurate than before.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "a6b43e382568a49cc64291bfaddf896652d44f70", "tree": "b7ef950c5d704dc72e054ad621fa34d82ae4f9cf", "parents": [ "cc3e1bea5d87635c519da657303690f5538bb4eb" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Wed Dec 23 07:48:08 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Dec 23 07:48:08 2009 -0500" }, "message": "ext4: fix unsigned long long printk warning in super.c\n\nsparc64 allmodconfig:\n\nfs/ext4/super.c: In function `lifetime_write_kbytes_show\u0027:\nfs/ext4/super.c:2174: warning: long long unsigned int format, long unsigned int arg (arg 4)\nfs/ext4/super.c:2174: warning: long long unsigned int format, long unsigned int arg (arg 4)\n\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "51b7e3c9fbe7d22d4e355101e9a73b44fc5c9feb", "tree": "490f2fd007d657a09ad33820c85ff75ee15bce96", "parents": [ "84c664730374248adaf420c0846a6158d64413c7" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Dec 21 10:56:09 2009 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Dec 21 10:56:09 2009 -0500" }, "message": "ext4: add module aliases for ext2 and ext3\n\nAdd module aliases for ext2 and ext3 when CONFIG_EXT4_USE_FOR_EXT23 is\nset.
