XFS (which currently is the only user of iomap_write_delalloc_release) already holds invalidate_lock for most zeroing operations. To be able to avoid a deadlock it needs to stop taking the lock, but doing so in iomap would leak XFS locking details into iomap. To avoid this require the caller to hold invalidate_lock when calling iomap_write_delalloc_release instead of taking it there. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.
