Zhao Lei c99f1b0c6c btrfs: Support busy loop of write and delete ... Reproduce: while true; do dd if=/dev/zero of=/mnt/btrfs/file count=[75% fs_size] rm /mnt/btrfs/file done Then we can see above loop failed on NO_SPACE. It it long-term problem since very beginning, because delayed-iput after rm are not run. We already have commit_transaction() in alloc_space code, but it is not triggered in above case. This patch trigger commit_transaction() to run delayed-iput and reflash pinned-space to to make write success. It is based on previous fix of delayed-iput in commit_transaction(), need to be applied on top of: btrfs: Fix NO_SPACE bug caused by delayed-iput Signed-off-by: Zhao Lei <zhaolei@cn.fujitsu.com> Signed-off-by: Chris Mason <clm@fb.com>		2015-04-13 07:31:10 -07:00
