  "message": "Btrfs: cache the extent state everywhere we possibly can V2\n\nThis patch just goes through and fixes everybody that does\n\nlock_extent()\nblah\nunlock_extent()\n\nto use\n\nlock_extent_bits()\nblah\nunlock_extent_cached()\n\nand pass around a extent_state so we only have to do the searches once per\nfunction.  This gives me about a 3 mb/s boots on my random write test.  I have\nnot converted some things, like the relocation and ioctl\u0027s, since they aren\u0027t\nheavily used and the relocation stuff is in the middle of being re-written.  I\nalso changed the clear_extent_bit() to only unset the cached state if we are\nclearing EXTENT_LOCKED and related stuff, so we can do things like this\n\nlock_extent_bits()\nclear delalloc bits\nunlock_extent_cached()\n\nwithout losing our cached state.  I tested this thoroughly and turned on\nLEAK_DEBUG to make sure we weren\u0027t leaking extent states, everything worked out\nfine.\n\nSigned-off-by: Josef Bacik \u003cjosef@redhat.com\u003e\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n",
