      "message": "Btrfs: do extent allocation and reference count updates in the background\n\nThe extent allocation tree maintains a reference count and full\nback reference information for every extent allocated in the\nfilesystem.  For subvolume and snapshot trees, every time\na block goes through COW, the new copy of the block adds a reference\non every block it points to.\n\nIf a btree node points to 150 leaves, then the COW code needs to go\nand add backrefs on 150 different extents, which might be spread all\nover the extent allocation tree.\n\nThese updates currently happen during btrfs_cow_block, and most COWs\nhappen during btrfs_search_slot.  btrfs_search_slot has locks held\non both the parent and the node we are COWing, and so we really want\nto avoid IO during the COW if we can.\n\nThis commit adds an rbtree of pending reference count updates and extent\nallocations.  The tree is ordered by byte number of the extent and byte number\nof the parent for the back reference.  The tree allows us to:\n\n1) Modify back references in something close to disk order, reducing seeks\n2) Significantly reduce the number of modifications made as block pointers\nare balanced around\n3) Do all of the extent insertion and back reference modifications outside\nof the performance critical btrfs_search_slot code.\n\n#3 has the added benefit of greatly reducing the btrfs stack footprint.\nThe extent allocation tree modifications are done without the deep\n(and somewhat recursive) call chains used in the past.\n\nThese delayed back reference updates must be done before the transaction\ncommits, and so the rbtree is tied to the transaction.  Throttling is\nimplemented to help keep the queue of backrefs at a reasonable size.\n\nSince there was a similar mechanism in place for the extent tree\nextents, that is removed and replaced by the delayed reference tree.\n\nYan Zheng \u003cyan.zheng@oracle.com\u003e helped review and fixup this code.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n"

      "message": "Btrfs: Add zlib compression support\n\nThis is a large change for adding compression on reading and writing,\nboth for inline and regular extents.  It does some fairly large\nsurgery to the writeback paths.\n\nCompression is off by default and enabled by mount -o compress.  Even\nwhen the -o compress mount option is not used, it is possible to read\ncompressed extents off the disk.\n\nIf compression for a given set of pages fails to make them smaller, the\nfile is flagged to avoid future compression attempts later.\n\n* While finding delalloc extents, the pages are locked before being sent down\nto the delalloc handler.  This allows the delalloc handler to do complex things\nsuch as cleaning the pages, marking them writeback and starting IO on their\nbehalf.\n\n* Inline extents are inserted at delalloc time now.  This allows us to compress\nthe data before inserting the inline extent, and it allows us to insert\nan inline extent that spans multiple pages.\n\n* All of the in-memory extent representations (extent_map.c, ordered-data.c etc)\nare changed to record both an in-memory size and an on disk size, as well\nas a flag for compression.\n\nFrom a disk format point of view, the extent pointers in the file are changed\nto record the on disk size of a given extent and some encoding flags.\nSpace in the disk format is allocated for compression encoding, as well\nas encryption and a generic \u0027other\u0027 field.  Neither the encryption or the\n\u0027other\u0027 field are currently used.\n\nIn order to limit the amount of data read for a single random read in the\nfile, the size of a compressed extent is limited to 128k.  This is a\nsoftware only limit, the disk format supports u64 sized compressed extents.\n\nIn order to limit the ram consumed while processing extents, the uncompressed\nsize of a compressed extent is limited to 256k.  This is a software only limit\nand will be subject to tuning later.\n\nChecksumming is still done on compressed extents, and it is done on the\nuncompressed version of the data.  This way additional encodings can be\nlayered on without having to figure out which encoding to checksum.\n\nCompression happens at delalloc time, which is basically singled threaded because\nit is usually done by a single pdflush thread.  This makes it tricky to\nspread the compression load across all the cpus on the box.  We\u0027ll have to\nlook at parallel pdflush walks of dirty inodes at a later time.\n\nDecompression is hooked into readpages and it does spread across CPUs nicely.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n"

      "message": "Btrfs: free space accounting redo\n\n1) replace the per fs_info extent_io_tree that tracked free space with two\nrb-trees per block group to track free space areas via offset and size.  The\nreason to do this is because most allocations come with a hint byte where to\nstart, so we can usually find a chunk of free space at that hint byte to satisfy\nthe allocation and get good space packing.  If we cannot find free space at or\nafter the given offset we fall back on looking for a chunk of the given size as\nclose to that given offset as possible.  When we fall back on the size search we\nalso try to find a slot as close to the size we want as possible, to avoid\nbreaking small chunks off of huge areas if possible.\n\n2) remove the extent_io_tree that tracked the block group cache from fs_info and\nreplaced it with an rb-tree thats tracks block group cache via offset.  also\nadded a per space_info list that tracks the block group cache for the particular\nspace so we can lookup related block groups easily.\n\n3) cleaned up the allocation code to make it a little easier to read and a\nlittle less complicated.  Basically there are 3 steps, first look from our\nprovided hint.  If we couldn\u0027t find from that given hint, start back at our\noriginal search start and look for space from there.  If that fails try to\nallocate space if we can and start looking again.  If not we\u0027re screwed and need\nto start over again.\n\n4) small fixes.  there were some issues in volumes.c where we wouldn\u0027t allocate\nthe rest of the disk.  fixed cow_file_range to actually pass the alloc_hint,\nwhich has helped a good bit in making the fs_mark test I run have semi-normal\nresults as we run out of space.  Generally with data allocations we don\u0027t track\nwhere we last allocated from, so everytime we did a data allocation we\u0027d search\nthrough every block group that we have looking for free space.  Now searching a\nblock group with no free space isn\u0027t terribly time consuming, it was causing a\nslight degradation as we got more data block groups.  The alloc_hint has fixed\nthis slight degredation and made things semi-normal.\n\nThere is still one nagging problem I\u0027m working on where we will get ENOSPC when\nthere is definitely plenty of space.  This only happens with metadata\nallocations, and only when we are almost full.  So you generally hit the 85%\nmark first, but sometimes you\u0027ll hit the BUG before you hit the 85% wall.  I\u0027m\nstill tracking it down, but until then this seems to be pretty stable and make a\nsignificant performance gain.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n"

But, workqueues only schedule work on the\nsame CPU that queued the work, giving them a limited benefit for systems with\nhigher CPU counts.\n\nThis code adds a generic facility to schedule work with pools of kthreads,\nand changes the bio submission code to queue bios up.  The queueing is\nimportant to make sure large numbers of procs on the system don\u0027t\nturn streaming workloads into random workloads by sending IO down\nconcurrently.\n\nThe end result of all of this is much higher performance (and CPU usage) when\ndoing checksumming on large machines.  Two worker pools are created,\none for writes and one for endio processing.  The two could deadlock if\nwe tried to service both from a single pool.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n"
