This also works\naround limitations in the ext4 block allocator, which can\u0027t allocate\nmore than 2048 blocks at a time. So we need to defeat the round-robin\ncharacteristics of the writeback code and try to write out as many\nblocks in one inode before allowing the writeback code to move on to\nanother inode. We add a a new per-filesystem tunable,\nmax_writeback_mb_bump, which caps this to a default of 128mb per\ninode.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "0d54b217a247f39605361f867fefbb9e099a5432", "tree": "5af6a2cc4cbc6c327e735ac5edb642d47a1f0013", "parents": [ "61e225dc341107be304fd1088146c2a5e88ff9e0" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Mon Sep 21 17:01:09 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 22 07:17:24 2009 -0700" }, "message": "const: make struct super_block::s_qcop const\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "61e225dc341107be304fd1088146c2a5e88ff9e0", "tree": "e6d3e1dc5506e232497f17721175a081a5306b5b", "parents": [ "00d3803b656a5f0935518d746f6bb27d5181d29d" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Mon Sep 21 17:01:08 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 22 07:17:24 2009 -0700" }, "message": "const: make struct super_block::dq_op const\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "fb0a387dcdcd21aab1b09ee7fd80b7c979bdbbfd", "tree": "dcb12c5fce8f7ccb8b183936ea71a29aba3f3846", "parents": [ "c40ce3c9ea97425a12d7e44031a98fe50add6fc1" ], "author": { "name": "Eric Sandeen", "email": "sandeen@redhat.com", "time": "Wed Sep 16 14:45:10 2009 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Wed Sep 16 14:45:10 2009 -0400" }, "message": "ext4: limit block allocations for indirect-block files to \u003c 2^32\n\nToday, the ext4 allocator will happily allocate blocks past\n2^32 for indirect-block files, which results in the block\nnumbers getting truncated, and corruption ensues.\n\nThis patch limits such allocations to \u003c 2^32, and adds\nBUG_ONs if we do get blocks larger than that.\n\nThis should address RH Bug 519471, ext4 bitmap allocator \nmust limit blocks to \u003c 2^32\n\n* ext4_find_goal() is modified to choose a goal \u003c UINT_MAX,\n so that our starting point is in an acceptable range.\n\n* ext4_xattr_block_set() is modified such that the goal block\n is \u003c UINT_MAX, as above.\n\n* ext4_mb_regular_allocator() is modified so that the group\n search does not continue into groups which are too high\n\n* ext4_mb_use_preallocated() has a check that we don\u0027t use\n preallocated space which is too far out\n\n* ext4_alloc_blocks() and ext4_xattr_block_set() add some BUG_ONs\n\nNo attempt has been made to limit inode locations to \u003c 2^32,\nso we may wind up with blocks far from their inodes.
