When anon_inode_getfile() failed the cleanup was correctly performed but the error code was not propagated to callers of copy_process() causing them to operate on a nonsensical pointer. The fix is a simple on-liner which makes sure that a proper negative error code is returned from copy_process(). syzkaller has also verified that the bug is not reproducible with the patch in this branch. Please consider pulling these changes from the signed for-linus-20190701 tag. Thanks!
