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.

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.
