These are\n already shipping in the sles kernel, and they give btrfs the ability\n to abort transactions and go readonly on errors. It involves a lot of\n churn as they clarify BUG_ONs, and remove the ones we now properly\n deal with.\n\n Josef reworked the way our metadata interacts with the page cache.\n page-\u003eprivate now points to the btrfs extent_buffer object, which\n makes everything faster. He changed it so we write an whole extent\n buffer at a time instead of allowing individual pages to go down,,\n which will be important for the raid5/6 code (for the 3.5 merge\n window ;)\n\n Josef also made us more aggressive about dropping pages for metadata\n blocks that were freed due to COW. Overall, our metadata caching is\n much faster now.\n\n We\u0027ve integrated my patch for metadata bigger than the page size.\n This allows metadata blocks up to 64KB in size. In practice 16K and\n 32K seem to work best. For workloads with lots of metadata, this cuts\n down the size of the extent allocation tree dramatically and fragments\n much less.\n\n Scrub was updated to support the larger block sizes, which ended up\n being a fairly large change (thanks Stefan Behrens).\n\n We also have an assortment of fixes and updates, especially to the\n balancing code (Ilya Dryomov), the back ref walker (Jan Schmidt) and\n the defragging code (Liu Bo).\"\n\nFixed up trivial conflicts in fs/btrfs/scrub.c that were just due to\nremoval of the second argument to k[un]map_atomic() in commit\n7ac687d9e047.\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (75 commits)\n Btrfs: update the checks for mixed block groups with big metadata blocks\n Btrfs: update to the right index of defragment\n Btrfs: do not bother to defrag an extent if it is a big real extent\n Btrfs: add a check to decide if we should defrag the range\n Btrfs: fix recursive defragment with autodefrag option\n Btrfs: fix the mismatch of page-\u003emapping\n Btrfs: fix race between direct io and autodefrag\n Btrfs: fix deadlock during allocating chunks\n Btrfs: show useful info in space reservation tracepoint\n Btrfs: don\u0027t use crc items bigger than 4KB\n Btrfs: flush out and clean up any block device pages during mount\n btrfs: disallow unequal data/metadata blocksize for mixed block groups\n Btrfs: enhance superblock sanity checks\n Btrfs: change scrub to support big blocks\n Btrfs: minor cleanup in scrub\n Btrfs: introduce common define for max number of mirrors\n Btrfs: fix infinite loop in btrfs_shrink_device()\n Btrfs: fix memory leak in resolver code\n Btrfs: allow dup for data chunks in mixed mode\n Btrfs: validate target profiles only if we are going to use them\n ...\n" }, { "commit": "4cb13e5d6ecc47b91b24a35f8fbc2c9f33d075fe", "tree": "c1654f1b2f029c8cfd5385568b37f90a0b47f3c4", "parents": [ "1f12bd063285b059cb63315d1424dae1ddd87a64" ], "author": { "name": "Liu Bo", "email": "liubo2009@cn.fujitsu.com", "time": "Thu Mar 29 09:57:45 2012 -0400" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Thu Mar 29 09:57:45 2012 -0400" }, "message": "Btrfs: fix recursive defragment with autodefrag option\n\n$ mkfs.btrfs disk\n$ mount disk /mnt -o autodefrag\n$ dd if\u003d/dev/zero of\u003d/mnt/foobar bs\u003d4k count\u003d10 2\u003e/dev/null \u0026\u0026 sync\n$ for i in `seq 9 -2 0`; do dd if\u003d/dev/zero of\u003d/mnt/foobar bs\u003d4k count\u003d1 \\\n seek\u003d$i conv\u003dnotrunc 2\u003e /dev/null; done \u0026\u0026 sync\n\nthen we\u0027ll get to defrag \"foobar\" again and again.\nSo does option \"-o autodefrag,compress\".\n\nReasons:\nWhen the cleaner kthread gets to fetch inodes from the defrag tree and defrag\nthem, it will dirty pages and submit them, this will comes to another DATA COW\nwhere the processing inode will be inserted to the defrag tree again.\n\nThis patch sets a rule for COW code, i.e. insert an inode when we\u0027re really\ngoing to make some defragments.\n\nSigned-off-by: Liu Bo \u003cliubo2009@cn.fujitsu.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "1d4284bd6e8d7dd1d5521a6747bdb6dc1caf0225", "tree": "a7dde6312ec24eb6368cad7a3efedbf368a5a70c", "parents": [ "b5d67f64f9bc656970dacba245410f0faedad18e", "65139ed99234d8505948cdb7a835452eb5c191f9" ], "author": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Wed Mar 28 20:31:37 2012 -0400" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Wed Mar 28 20:31:37 2012 -0400" }, "message": "Merge branch \u0027error-handling\u0027 into for-linus\n\nConflicts:\n\tfs/btrfs/ctree.c\n\tfs/btrfs/disk-io.c\n\tfs/btrfs/extent-tree.c\n\tfs/btrfs/extent_io.c\n\tfs/btrfs/extent_io.h\n\tfs/btrfs/inode.c\n\tfs/btrfs/scrub.c\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "0b32f4bbb423f02acee6d43cd442f5f0775db7e0", "tree": "1963e5420071e70274bf77c05373dabd43bac675", "parents": [ "5df4235ea15bd39f441ef334d8329b3d46b2cc57" ], "author": { "name": "Josef Bacik", "email": "josef@redhat.com", "time": "Tue Mar 13 09:38:00 2012 -0400" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Mon Mar 26 17:04:23 2012 -0400" }, "message": "Btrfs: ensure an entire eb is written at once\n\nThis patch simplifies how we track our extent buffers.

This is\n required since the fixup worker can fail with -ENOSPC and the page\n will have already been redirtied. That causes an Oops in\n drop_outstanding_extents later. Retrying the fixup worker could\n lead to an infinite loop. Deferring the page redirty also saves us\n some cycles since the page would be stuck in a resubmit-redirty loop\n until the fixup worker completes. It\u0027s not harmful, just wasteful.\n - If the fixup worker fails, we mark the page and mapping as errored,\n and end the writeback, similar to what we would do had the page\n actually been submitted to writeback.\n\nSigned-off-by: Jeff Mahoney \u003cjeffm@suse.com\u003e\n" }, { "commit": "67d2433ee7aa631bc3ab14c2af6bbc1d44d13a00", "tree": "eb29e1489f9f4a99308e08568328de73fb89fc2e", "parents": [ "1c36ab1a318ab5b3b502e7e4fff3628d1a97861f", "9998eb703490589c3e8f1bf09b15203156776edb" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jan 28 17:00:19 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jan 28 17:00:19 2012 -0800" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs:\n Btrfs: fix reservations in btrfs_page_mkwrite\n Btrfs: advance window_start if we\u0027re using a bitmap\n btrfs: mask out gfp flags in releasepage\n Btrfs: fix enospc error caused by wrong checks of the chunk\n Btrfs: do not defrag a file partially\n Btrfs: fix warning for 32-bit build of fs/btrfs/check-integrity.c\n Btrfs: use cluster-\u003ewindow_start when allocating from a cluster bitmap\n Btrfs: Check for NULL page in extent_range_uptodate\n btrfs: Fix busyloops in transaction waiting code\n Btrfs: make sure a bitmap has enough bytes\n Btrfs: fix uninit warning in backref.c\n" }, { "commit": "9998eb703490589c3e8f1bf09b15203156776edb", "tree": "5d01f0e7efae049b9be80292c93fe30f11eeefd1", "parents": [ "9b23062840e7c685ef0a0b561285d6e3a3b6811b" ], "author": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Wed Jan 25 13:47:40 2012 -0500" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Fri Jan 27 10:44:44 2012 -0500" }, "message": "Btrfs: fix reservations in btrfs_page_mkwrite\n\nJosef fixed btrfs_page_mkwrite to properly release reserved\nextents if there was an error.

This took me down a huge\nrabbit hole and it turns out the way we deal with reserved_extents is wrong,\nwe need to only be setting it if the reservation succeeds, otherwise the free()\nmethod will come in and unreserve space that isn\u0027t actually reserved yet, which\ncan lead to other warnings and such. The math was all working out right in the\nend, but it caused all sorts of other issues in addition to making my scripts\nyell and scream and generally make it impossible for me to track down the\noriginal issue I was looking for. The other problem is with our error handling\nin the reservation code. There are two cases that we need to deal with\n\n1) We raced with free. In this case free won\u0027t free anything because csum_bytes\nis modified before we dro the lock in our reservation path, so free rightly\ndoesn\u0027t release any space because the reservation code may be depending on that\nreservation. However if we fail, we need the reservation side to do the free at\nthat point since that space is no longer in use. So as it stands the code was\ndoing this fine and it worked out, except in case #2\n\n2) We don\u0027t race with free. Nobody comes in and changes anything, and our\nreservation fails. In this case we didn\u0027t reserve anything anyway and we just\nneed to clean up csum_bytes but not free anything. So we keep track of\ncsum_bytes before we drop the lock and if it hasn\u0027t changed we know we can just\ndecrement csum_bytes and carry on.\n\nBecause of the case where we can race with free()\u0027s since we have to drop our\nspin_lock to do the reservation, I\u0027m going to serialize all reservations with\nthe i_mutex. We already get this for free in the heavy use paths, truncate and\nfile write all hold the i_mutex, just needed to add it to page_mkwrite and\nvarious ioctl/balance things.

This is\nbecause a bunch of people call mark_inode_dirty, which is void so we can\u0027t\nreturn ENOSPC.

So copy file_update_time into btrfs so we can\ncall btrfs_dirty_inode directly and return an error if we get one appropriately.\n\n2) fix symlinks to use btrfs_setattr for -\u003esetattr. For some reason we weren\u0027t\nsetting -\u003esetattr for symlinks, even though we should have been. This catches\none of the cases where we were getting errors in mark_inode_dirty.\n\n3) Fix btrfs_setattr and btrfs_setsize to call btrfs_dirty_inode directly\ninstead of mark_inode_dirty.

This is because\nwe try to steal from the delalloc block rsv to satisfy a reservation to update\nthe inode. The problem with this is we don\u0027t explicitly save space for updating\nthe inode when doing delalloc. This is kind of a problem and we\u0027ve gotten away\nwith this because way back when we just stole from the delalloc reserve without\nany questions, and this worked out fine because generally speaking the leaf had\nbeen modified either by the mtime update when we did the original write or\nbecause we just updated the leaf when we inserted the file extent item, only on\nrare occasions had the leaf not actually been modified, and that was still ok\nbecause we\u0027d just use a block or two out of the over-reservation that is\ndelalloc.\n\nThen came the delayed inode stuff. This is amazing, except it wants a full\nreservation for updating the inode since it may do it at some point down the\nroad after we\u0027ve written the blocks and we have to recow everything again. This\nworked out because the delayed inode stuff just stole from the global reserve,\nthat is until recently when I changed that because it caused other problems.\n\nSo here we are, we\u0027re doing everything right and being screwed for it. So take\nan extra reservation for the inode at delalloc reservation time and carry it\nthrough the life of the delalloc reservation. If we need it we can steal it in\nthe delayed inode stuff.

I was migrating the bytes from the transaction reserve to the\nglobal reserve and then releasing from the global reserve in\nbtrfs_end_transaction(). The problem with this is that a migrate will jack up\nthe size for the destination, but leave the size alone for the source, with the\nidea that you can do a release normally on the source and it all washes out, and\nthen you can do a release again on the destination and it works out right. My\nway was skipping the release on the trans_block_rsv which still had the jacked\nup size from our original reservation. So instead release manually from the\nglobal reserve if this transaction was using it, and then set the\ntrans-\u003eblock_rsv back to the trans_block_rsv so that btrfs_end_transaction\ncleans everything up properly.
