[PATCH v3 0/2] btrfs: qgroup race fix and cleanup

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

Fix a race that leads to a use-after-free plus cleanup no longer used
qgroup_ulist.

V2: Update patch 1/2 to return -ENOTCONN if quotas are disabled when
    we try to start the rescan worker.
V3: Make patch 1/2 actually return -ENOTCONN.

Filipe Manana (2):
  btrfs: qgroup: fix race between quota disable and quota rescan ioctl
  btrfs: qgroup: remove no longer used fs_info->qgroup_ulist
