include/linux/huge_mm.h: return NULL instead of false for pmd_trans_huge_lock()
The return value of pmd_trans_huge_lock() is a pointer, not a boolean value, so use NULL instead of false as the return value. Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> Acked-by: Kirill A. Shutemov <kirill.shutemov@linux.intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
