From 0aab29b85478b994422f1551ce36e5640b09db2b Mon Sep 17 00:00:00 2001 From: Chaitanya Kulkarni Date: Tue, 15 Feb 2022 13:33:08 -0800 Subject: [PATCH] loop: remove extra variable in lo_fallocate() The local variable q is used to pass it to the blk_queue_discard(). We can get away with using lo->lo_queue instead of storing in a local variable which is not used anywhere else. No functional change in this patch.
