Robbie Ko ec125cfb7a Btrfs: fix deadlock caused by fsync when logging directory entries ... While logging new directory entries, at tree-log.c:log_new_dir_dentries(), after we call btrfs_search_forward() we get a leaf with a read lock on it, and without unlocking that leaf we can end up calling btrfs_iget() to get an inode pointer. The later (btrfs_iget()) can end up doing a read-only search on the same tree again, if the inode is not in memory already, which ends up causing a deadlock if some other task in the meanwhile started a write search on the tree and is attempting to write lock the same leaf that btrfs_search_forward() locked while holding write locks on upper levels of the tree blocking the read search from btrfs_iget(). In this scenario we get a deadlock. So fix this by releasing the search path before calling btrfs_iget() at tree-log.c:log_new_dir_dentries().
