btrfsprogs/0022-btrfs-progs-zero-out-structures-before-calling-ioctl.patch
David Sterba 3ee7e4de90 Accepting request 259501 from home:dsterba:branches:filesystems
- version 3.17
  - check: --init-csum-tree acutally does something useful, rebuilds the whole
    csum tree
  - /dev scanning for btrfs devices is gone
  - /proc/partitions scanning is gone, blkid is used exclusively
  - new subcommand subvolume sync
  - filesystem df: new options to set unit format
  - convert: allow to copy label from the origin, or specify a new one

(not all local patches are upstream, maybe next time)
