From e45105772db41c5318b2a7ec1c420183183414e3 Mon Sep 17 00:00:00 2001 From: Daeho Jeong Date: Sat, 5 Aug 2017 13:11:57 -0400 Subject: [PATCH] ext4: release discard bio after sending discard commands We've changed the discard command handling into parallel manner. But, in this change, I forgot decreasing the usage count of the bio which was used to send discard request. I'm sorry about that.
