From ce5f33a58d3510400859ca408ef650212a96addd Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Wed, 15 Mar 2017 14:05:13 +1100 Subject: [PATCH] Revert "md/raid5: limit request size according to implementation limits" This reverts commit b49255d5c7ece9fdb7c0e3e3bd039c0f5c31e269. Now that raid5 doesn't abuse bi_phys_segments any more, we no longer need to impose these limits.
