The patch titled Subject: mm/mmap.c: use IS_ERR_VALUE() to check return value of get_unmapped_area() has been removed from the -mm tree. Its filename was mm-mmapc-use-is_err_value-to-check-return-value-of-get_unmapped_area.patch This patch was dropped because it had testing failures ------------------------------------------------------ From: Gaowei Pu <pugaowei@xxxxxxxxx> Subject: mm/mmap.c: use IS_ERR_VALUE() to check return value of get_unmapped_area() get_unmapped_area() already covers the offset_in_page() check and returns with an error ptr. So replace offset_in_page() with IS_ERR_VALUE().
