[PATCH 2/4] Btrfs: fix deadlock on sb->s_umount when doing umount
The reason the deadlock is that:
Task Btrfs-cleaner
umount()
down_write(&s->s_umount)
sync_filesystem()
do auto-defragment and produce
lots of dirty pages
close_ctree()
wait for the end of
btrfs-cleaner
start_transaction
reserve space
shrink_delalloc()
writeback_inodes_sb_nr_if_idle()
