This code was added in 492bb6deee34 ("Btrfs: Hold a reference on bios
during submit_bio, add some extra bio checks"). However, holding a
reference on a bio is necessary only if it's going to be referenced
after the submit_bio returns and the bio is completed. In this
particular instance this is not the case so there is no need to hold
an extra reference since we directly return.Signed-off-by: Nikolay Borisov <[email protected]> --- fs/btrfs/volumes.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/fs/btrfs/volumes.c b/fs/btrfs/volumes.c index 49810b70afd3..13827ff648ec 100644 --- a/fs/btrfs/volumes.c +++ b/fs/btrfs/volumes.c @@ -6069,9 +6069,7 @@ static noinline void btrfs_schedule_bio(struct btrfs_device *device, /* don't bother with additional async steps for reads, right now */ if (bio_op(bio) == REQ_OP_READ) { - bio_get(bio); btrfsic_submit_bio(bio); - bio_put(bio); return; } -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
