Subject: mm: simplify list initialization in barn_shrink()
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6adf4b11fa50a31dc1c3791131020e624c6f139d;p=thirdparty%2Flinux.git

mm: simplify list initialization in barn_shrink()

In barn_shrink(), use LIST_HEAD() to declare and initialize the
list_head in one step instead of using INIT_LIST_HEAD() separately.

No functional change.
