From 2bb4cd5cc472b191a46938becb7dafdd44644329 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Tue, 14 Jul 2015 08:15:12 -0600 Subject: block: have drivers use blk_queue_max_discard_sectors() Some drivers use it now, others just set the limits field manually. But in preparation for splitting this into a hard and soft limit, ensure that they all call the proper function for setting the hw limit for discards.
