Subject: f2fs: relocate the tracepoint for background_gc
X-Git-Tag: firefly_0821_release~176^2~797^2~8
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=84e4214f0868ae77771837d0ed4cc6eff10738ba;p=firefly-linux-kernel-4.4.55.git

f2fs: relocate the tracepoint for background_gc

Once f2fs_gc is done, wait_ms is changed once more.
So, its tracepoint would be located after it.
