Date: Tue, 11 Sep 2018 19:28:59 +0800	[thread overview]
Message-ID: <20180911112903.25985-1-lufq.fnst@cn.fujitsu.com> (raw)

This patchset will add the BTRFS_IOC_SUBVOL_UNDELETE ioctl for online
btrfs subvolume undelete.

And using the online_undelete version of btrfs-progs, user can recover
the subvolume given by <subvol_id> to the directory given by <dest>. The
optional parameter [-n <name>] can be used to set the name of the
recovered subvolume.

# btrfs subvolume undelete [-n <name>] <subvol_id> <dest>

btrfs online undelete version:
https://github.com/littleroad/linux.git undelete

btrfs-progs online undelete version:
https://github.com/littleroad/btrfs-progs.git online_undelete

Issue: #82

  btrfs: factor out btrfs_link_subvol from create_subvol
  btrfs: don't BUG_ON() in btrfs_link_subvol()
  btrfs: undelete: introduce btrfs_undelete_subvolume
  btrfs: undelete: Add BTRFS_IOCTL_SUBVOL_UNDELETE ioctl
