Subject: btrfs: Cleanup the btrfs_workqueue related function type
X-Git-Tag: firefly_0821_release~176^2~3883^2~59
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=6db8914f9763d3f0a7610b497d44f93a4c17e62e;p=firefly-linux-kernel-4.4.55.git

btrfs: Cleanup the btrfs_workqueue related function type

The new btrfs_workqueue still use open-coded function defition,
this patch will change them into btrfs_func_t type which is much the
same as kernel workqueue.
