At transaction commit time,\nthe old root of the subvolume is recorded in a \"dead root\" data structure,\nand the btree it points to is later walked, dropping reference counts\nand freeing any blocks where the reference count goes to 0.\n\nThe increments done during cow and decrements done after commit cancel out,\nand the walk is a very expensive way to go about freeing the blocks that\nare no longer referenced by the new btree root. This commit reduces the\ntransaction overhead by avoiding the need for dead root records.\n\nWhen a non-shared tree block is cow\u0027d, we free the old block at once, and the\nnew block inherits old block\u0027s references. When a tree block with reference\ncount \u003e 1 is cow\u0027d, we increase the reference counts of all extents\nthe new block points to by one, and decrease the old block\u0027s reference count by\none.\n\nThis dead tree avoidance code removes the need to modify the reference\ncounts of lower level extents when a non-shared tree block is cow\u0027d.\nBut we still need to update back ref for all pointers in the block.\nThis is because the location of the block is recorded in the back ref\nitem.\n\nWe can solve this by introducing a new type of back ref. The new\nback ref provides information about pointer\u0027s key, level and in which\ntree the pointer lives. This information allow us to find the pointer\nby searching the tree. The shortcoming of the new back ref is that it\nonly works for pointers in tree blocks referenced by their owner trees.\n\nThis is mostly a problem for snapshots, where resolving one of these\nfuzzy back references would be O(number_of_snapshots) and quite slow.\nThe solution used here is to use the fuzzy back references in the common\ncase where a given tree block is only referenced by one root,\nand use the full back references when multiple roots have a reference\non a given block.\n\nThis commit adds per subvolume red-black tree to keep trace of cached\ninodes. The red-black tree helps the balancing code to find cached\ninodes whose inode numbers within a given range.\n\nThis commit improves the balancing code by introducing several data\nstructures to keep the state of balancing. The most important one\nis the back ref cache. It caches how the upper level tree blocks are\nreferenced. This greatly reduce the overhead of checking back ref.\n\nThe improved balancing code scales significantly better with a large\nnumber of snapshots.\n\nThis is a very large commit and was written in a number of\npieces. But, they depend heavily on the disk format change and were\nsquashed together to make sure git bisect didn\u0027t end up in a\nbad state wrt space balancing or the format change.\n\nSigned-off-by: Yan Zheng \u003czheng.yan@oracle.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "5c939df56c3ea018b58e5aa76181284c2053d699", "tree": "6d97449faa69c96998833fcb56a3b65050d34354", "parents": [ "07a2039b8eb0af4ff464efd3dfd95de5c02648c6" ], "author": { "name": "Yan Zheng", "email": "zheng.yan@oracle.com", "time": "Wed May 27 09:16:03 2009 -0400" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Wed Jun 10 11:29:46 2009 -0400" }, "message": "btrfs: Fix set/clear_extent_bit for \u0027end \u003d\u003d (u64)-1\u0027\n\nThere are some \u0027start \u003d state-\u003eend + 1;\u0027 like code in set_extent_bit\nand clear_extent_bit.

We were\nconcerned about side effects from this change and one has been identified.\n\nI saw several error messages.\n\nThey cause autofs to become quite confused and don\u0027t really point to the\nactual problem.\n\nThings like:\n\nhandle_packet_missing_direct:1376: can\u0027t find map entry for (43,1827932)\n\nwhich is usually totally fatal (although in this case it wouldn\u0027t be\nexcept that I treat is as such because it normally is).\n\ndo_mount_direct: direct trigger not valid or already mounted\n/test/nested/g3c/s1/ss1\n\nwhich is recoverable, however if this problem is at play it can cause\nautofs to become quite confused as to the dependencies in the mount tree\nbecause mount triggers end up mounted multiple times. It\u0027s hard to\naccurately check for this over mounting case and automount shouldn\u0027t need\nto if the kernel module is doing its job.\n\nThere was one other message, similar in consequence of this last one but I\ncan\u0027t locate a log example just now.\n\nWhen checking if a mount has already completed prior to adding a new mount\nrequest to the wait queue we check if the dentry is hashed and, if so, if\nit is a mount point. But, if a mount successfully completed while we\nslept on the wait queue mutex the dentry must exist for the mount to have\ncompleted so the test is not really needed.\n\nMounts can also be done on top of a global root dentry, so for the above\ncase, where a mount request completes and the wait queue entry has already\nbeen removed, the hashed test returning false can cause an incorrect\ncallback to the daemon. Also, d_mountpoint() is not sufficient to check\nif a mount has completed for the multi-mount case when we don\u0027t have a\nreal mount at the base of the tree.\n\nSigned-off-by: Ian Kent

So ext2 and jfs\nwill try to calculate the number of blocks to map by taking stack\ngarbage and shifting it left by inode-\u003ei_blkbits. This should be\n*mostly* harmless (except the filesystem will do some unnneeded work)\nunless the stack garbage is less than filesystem\u0027s blocksize, in which\ncase maxblocks will be zero, and the attempt to find out whether or\nnot the filesystem has a hole at a given logical block will fail, and\nthe page cache entry might not get zero\u0027ed out.\n\nAlso if the stack garbage in in map_bh-\u003estate happens to have the\nBH_Mapped bit set, there could be an attempt to call readpage() on a\nnon-existent page, which could cause nobh_truncate_page() to return an\nerror when it should not.\n\nFix this by initializing map_bh-\u003estate and map_bh-\u003esize.\n\nFortunately, it\u0027s probably fairly unlikely that ext2 and jfs users\nmount with nobh these days.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nCc: Dave Kleikamp \u003cshaggy@linux.vnet.ibm.com\u003e\nCc: linux-fsdevel@vger.kernel.org\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "a3cb900cc408977a11519bc7c760f3e499079589", "tree": "e89cf76bf484081ea057b5362445a7ec667c0162", "parents": [ "65e31643115349fd7a81acbe75ec4a54d5df8aad" ], "author": { "name": "Alan Cox", "email": "alan@linux.intel.com", "time": "Wed May 13 15:02:27 2009 +0100" }, "committer": { "name": "Jeff Garzik", "email": "jgarzik@redhat.com", "time": "Fri Jun 05 17:10:54 2009 -0400" }, "message": "[libata] pata_ali: Use IGN_SIMPLEX\n\nSome ALi devices report simplex if they have been disabled and re-enabled, and\nrestoring the byte does not work.

Stracing dd reveals that it first does an\nmmap2, which makes 1GB worth of zero page mappings. Then it performs a\nread on those pages from /dev/zero, and finally it performs a write.\n\nThe machine died during the reads. Looking at the code, it was noticed\nthat /dev/zero\u0027s read operation had been changed by\n557ed1fa2620dc119adb86b34c614e152a629a80 (\"remove ZERO_PAGE\") from giving\nzero page mappings to actually zeroing the page.\n\nThe zeroing of the pages causes physical pages to be allocated to the\nprocess. But, when the process exhausts all the memory that it can, the\nkernel cannot kill it, as it is still in the kernel mode allocating more\nmemory. Consequently, the kernel eventually crashes.\n\nTo fix this, I propose that when a fatal signal is pending during\n/dev/zero read operation, we simply return and let the user process die.\n\nSigned-off-by: Salman Qazi \u003csqazi@google.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n[ Modified error return and comment trivially. - Linus]\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "44fb5511638938a2c37c895abc14df648ffc07e9", "tree": "0554a8a71403958b279ddcb601a3d0bb85943a59", "parents": [ "2cc3c559fb2fe8cecca82a517bc56e88b0c1effd" ], "author": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Thu Jun 04 15:34:51 2009 -0400" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Thu Jun 04 15:41:27 2009 -0400" }, "message": "Btrfs: Fix oops and use after free during space balancing\n\nThe btrfs allocator uses list_for_each to walk the available block\ngroups when searching for free blocks.
