Remove nid_lock from alloc_fresh_huge_page
The fix to that race in alloc_fresh_huge_page() which could give an illegal node ID did not need nid_lock at all: the fix was to replace static int nid by static int prev_nid and do the work on local int nid. nid_lock did make sure that racers strictly roundrobin the nodes, but that's not something we need to enforce strictly. Kill nid_lock. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
