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:
