Subject: btrfs: insert newly opened device to the end of the list
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b1b8e38622ea044ccdee0460253e428cb6e9038e;p=openwrt%2Fstaging%2Fblogic.git

btrfs: insert newly opened device to the end of the list

Add opened device to the tail of dev_alloc_list instead of head, so that
it maintains the same order as dev_list.
