ext4: yield during large unlinks
During large unlink operations on files with extents, we can use a lot
of CPU time. This adds a cond_resched() call when starting to examine
the next level of a multi-level extent tree. Multi-level extent trees
are rare in the first place, and this should rarely be executed.
