Btrfs progs release 3.18
Hi,
let me announce the release of btrfs-progs version 3.18. There are updates to UI and several enhancements of check/repair. About 100 commits from 14 contributors, thank you all!
Tarballs: https://www.kernel.org/pub/linux/kernel/people/kdave/btrfs-progs/
Git: git://git.kernel.org/pub/scm/linux/kernel/git/kdave/btrfs-progs.git
Major user-visible changes:
* mkfs - skinny-metadata feature is now on by default, first introduced in kernel 3.10
New subcommands:
* filesystem usage - give an overview of fs usage in a way that's more comprehensible than existing 'fi df'
* on kernels < 3.18: requires root due to restricted ioctl FS_INFO
* raid 5/6 numbers may be missing due to restricte ioctl (TREE_SEARCH)
* that's used to calculate the numbers
* device usage - more detailed information about per-device allocations
* same restrictions as for 'fi usage'
New features, options:
* check
* option to set a different tree root byte number
* ability to link lost files to lost+found, caused by a recent kernel bug
* repair of severely corrupted fs (use with care):
* recover from corrupted b-tree
* ability to rebuild inode items from other items
* improved rebuilding of extent tree with snapshots
* convert
* option to show progress
* subvol create - print the commit mode inline, print the global mode only if --verbose
Other updates:
* musl-libc build support
* bugfixes for coverity reports
* new test images, testing framework
* documentation
