User visible changes -------------------- * mkfs.btrfs --data dup People asked about duplicating data on a single device for a long time. There are no technical obstacles preventing that, so it got enabled with a warning about potential dangers when the device will not do the duplicated copies. See mkfs.btrfs section 'DUP PROFILES ON A SINGLE DEVICE'. * support balance filters added/enhanced in linux 4.4 * usage=min..max -- enhanced to take range * stripes=min..max -- new, filter by stripes for raid0/10/5/6 * limit=min..max -- enhanced to take range Due to backward compatibility, the range maximum for 'usage' is not inclusive as for the others, to keep the same behaviour as usage=N . * manual pages enhanced (btrfs, mkfs, mount, filesystem, balance) * error messages updates, rewordings -- some fstests may break due to that * added support for free-space-tree implementation of space cache this requires kernel 4.5 and is not recommended for non-developers yet * 'btrfs filesystem usage' works with mixed blockgroups Other: * installation to /usr/local -- this has unintentionally changed during conversion to autotools in 3.19 * check: fix a false alert where extent record has wrong metadata flag * improved stability on fuzzed/crafted images when reading sys array in superblock * build: the 'ar' tool is properly deteced during cross-compilation * debug-tree: option -t understands ids for tree root and chnuk tree * preparatory work for btrfs-convert rewrite * sparse, gcc warning fixes * more memory allocation failure handling * cleanups ... * more tests Bugfixes: * chunk recovery: fix floating point exception * chunk recovery: endianity bugfix during rebuild * mkfs with 64K pages and nodesize reported superblock checksum mismatch * check: properly reset nlink of multi-linked file Development cycle for 4.5 ------------------------- There are a few patchsets that did not make it to 4.4 and are currently at the top of my list. * feature compatibility of mkfs and kernel (Anand) * convert rework (Qu) -- more reivew needed, the pending patches are in branch foreign/qu/convert-rework * delete device by id (Anand) -- the kernel support is required, I need to look at the patches again * improved btrfs check progress There are a few more and I hope I'll get to them eventually. The bi-weekly stable releases are supposed to be resumed with bugfixes or docs updates.
