From ea7bd56fa309d10a41b1041827a63c0746c47554 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 2 Aug 2017 12:37:16 -0700 Subject: [PATCH] xfs: Fix leak of discard bio The bio describing discard operation is allocated by __blkdev_issue_discard() which returns us a reference to it. That reference is never released and thus we leak this bio. Drop the bio reference once it completes in xlog_discard_endio().
