Wong" Message-ID: <20170917210712.10804-10-hch@lst.de> From: Brian Foster commit cf2cb7845d6e101cb17bd62f8aa08cd514fc8988 upstream. XFS runs an eofblocks reclaim scan before returning an ENOSPC error to userspace for buffered writes. This facilitates aggressive speculative preallocation without causing user visible side effects such as premature ENOSPC. Run a cowblocks scan in the same situation to reclaim lingering COW fork preallocation throughout the filesystem. Signed-off-by: Brian Foster Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J.
