From 36f7894f66f286e454bf00d308b989c3423ba0da Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Wed, 13 Dec 2017 10:25:40 +0200 Subject: btrfs: Remove redundant pair of bio_get/set in __btrfs_submit_dio_bio The bio is not referenced after it has been submitted and the endio is going to consume the sole reference on successful submission. On error, the callers of __btrfs_submit_dio_bio do invoke bio_put so we don't leak it either.
