btrfs_rm_dev_item calls several function under an activa transaction, however it fails to abort it if an error happens. Fix this by adding explicit btrfs_abort_transaction/btrfs_end_transaction calls Signed-off-by: Nikolay Borisov <nborisov@suse.com> --- V3: * The path needs to be freed before the the transaction is comitted otherwise we will deadlock. fs/btrfs/volumes.c | 18 +++++++++++++++--- 1 file changed, 15 insertions(+), 3 deletions(-)
