Subject: [PATCH] md: Remove unnecessary printk when raid5 gets an unaligned read.
Date: Thu, 25 Jan 2007 16:06:16 +1100 [thread overview]
Message-ID: <1070125050616.21497@suse.de> (raw)

One more... (sorry about the dribs-and-drabs approach)

### Comments for Changeset
raid5_mergeable_bvec tries to ensure that raid5 never sees a read
request that does not fit within just one chunk. However as we
must always accept a single-page read, that is not always possible.
So when "in_chunk_boundary" fails, it might be unusual, but it is not
a problem and printing a message every time is a bad idea.
