      "message": "Btrfs: fix delayed insertion reservation\n\nWe all keep getting those stupid warnings from use_block_rsv when running\nstress.sh, and it\u0027s because the delayed insertion stuff is being stupid.  It\u0027s\nnot the delayed insertion stuffs fault, it\u0027s all just stupid.  When marking an\ninode dirty for oh say updating the time on it, we just do a\nbtrfs_join_transaction, which doesn\u0027t reserve any space.  This is stupid because\nwe\u0027re going to have to have space reserve to make this change, but we do it\nbecause it\u0027s fast because chances are we\u0027re going to call it over and over again\nand it doesn\u0027t matter.  Well thanks to the delayed insertion stuff this is\nmostly the case, so we do actually need to make this reservation.  So if\ntrans-\u003ebytes_reserved is 0 then try to do a normal reservation.  If not return\nENOSPC which will make the btrfs_dirty_inode start a proper transaction which\nwill let it do the whole ENOSPC dance and reserve enough space for the delayed\ninsertion to steal the reservation from the transaction.\n\nThe other stupid thing we do is not reserve space for the inode when writing to\nthe thing.  Usually this is ok since we have to update the time so we\u0027d have\nalready done all this work before we get to the endio stuff, so it doesn\u0027t\nmatter.  But this is stupid because we could write the data after the\ntransaction commits where we changed the mtime of the inode so we have to cow\nall the way down to the inode anyway.  This used to be masked by the delalloc\nreservation stuff, but because we delay the update it doesn\u0027t get masked in this\ncase.  So again the delayed insertion stuff bites us in the ass.  So if our\ntrans-\u003eblock_rsv is delalloc, just steal the reservation from the delalloc\nreserve.  Hopefully this won\u0027t bite us in the ass, but I\u0027ve said that before.\n\nWith this patch stress.sh no longer spits out those stupid warnings (famous last\nwords).

      "message": "Btrfs: release metadata from global reserve if we have to fallback for unlink\n\nI fixed a problem where we weren\u0027t reserving space for an orphan item when we\nhad to fallback to using the global reserve for an unlink, but I introduced\nanother problem.  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.  With this patch xfstest 83 doesn\u0027t emit warnings\nabout leaking space.

      "message": "Btrfs: fix extent pinning bugs in the tree log\n\nThe tree log had two important bugs that could cause corruptions after a\ncrash.  Sometimes we were allowing tree log blocks to be reused after\nthe tree log was committed but before the transaction commit was done.\n\nThis allowed a future metadata write to overwrite the tree log data.  It\nis fixed by adding a new variant of freeing reserved extents that always\npins them.  Credit goes to Stefan Behrens and Arne Jansen for many many\nhours spent tracking this bug down.\n\nDuring tree log replay, we do a pass through the tree log and pin all\nthe extents we find.  This makes sure the replay code won\u0027t go in and\nuse any of those blocks for new allocations during replay.  The problem\nis the free space cache isn\u0027t honoring these pinned extents.  So the\nallocator can end up handing them out, leading to all kinds of problems\nduring replay.\n\nThe fix here is to force any free space cache to load while we pin the\nextents, and then to make sure we remove the pinned extents from the\nfree space rbtree.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\nReported-by: Stefan Behrens \u003csbehrens@giantdisaster.de\u003e\n"
