Subject: f2fs: use unlikely for release case
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=fab2adee36039cdc2002ba3fe3a416c3f1bc6b52;p=openwrt%2Fstaging%2Fblogic.git

f2fs: use unlikely for release case

Since the variable release is only nonzero when another unlikely
case occurs, use unlikely() on it seems logical.
