The patch titled Subject: mm: respect arch_dup_mmap() return value has been removed from the -mm tree. Its filename was mm-respect-arch_dup_mmap-return-value.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------ From: Nadav Amit namit@vmware.com Subject: mm: respect arch_dup_mmap() return value

d70f2a14b72a4 ("include/linux/sched/mm.h: uninline mmdrop_async(), etc") ignored the return value of arch_dup_mmap(). As a result, on x86, a failure to duplicate the LDT (e.g., due to memory allocation error), would leave the duplicated memory mapping in an inconsistent state.

Fix by regarding the return value, as it was before the change.
