Subject: [md PATCH 07/14] Revert "md/raid5: limit request size according to implementation limits"
Date: Thu, 16 Feb 2017 15:39:02 +1100 [thread overview]
Message-ID: <148721994223.7521.17775131179521649771.stgit@noble> (raw)
In-Reply-To: <148721992248.7521.17160361058957519076.stgit@noble>
This reverts commit e8d7c33232e5fdfa761c3416539bc5b4acd12db5.
Now that raid5 doesn't abuse bi_phys_segments any more, we no longer
need to impose these limits.
