[PATCH 0/5] Btrfs: mount error handling fixes
A bunch of fixes (memory leaks, NULL pointer dereferences and devices
hanging in busy state) to sanitize error handling during mount sequence.
This is on top of for-linus + slyfox''s double-free fix.
Thanks,
Ilya
Ilya Dryomov (5):
Btrfs: fix memory leak in btrfs_parse_early_options()
Btrfs: fix subvol_name leak on error in btrfs_mount()
Btrfs: avoid null dereference and leaks
