acf49bb928 ("mm/mlock: split ClearPageLRU from page isolation .."): [ 36.045721] BUG: sleeping function called from invalid context at mm/rmap.c:1861

Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is

mm/mlock: split ClearPageLRU from page isolation and remain Mlocked guard
This is one of effort to split the PageLRU clear from old page
isolation.
This patch move the lru_lock after get PageLRU, which takes holding
PageLRU as precondition for page isolation, as a preparation for later
lru_lock replacment. So we have to unfold __munlock_isolate_lru_page.
__split_huge_page_refcount doesn't exist, but we still have to guard
PageMlocked in __split_huge_page_tail. that make code ugly and bear
few unrelated code in lock. anyway still removed few goto's to dress up
current code.
