-Subject: ring buffer: Propagate __rb_map_vma return value to caller
-
-From: Ankit Khushwaha <ankitkhushwaha.linux@gmail.com>
-
-commit de4cbd704731778a2dc833ce5a24b38e5d672c05 upstream.
-
-The return value from `__rb_map_vma()`, which rejects writable or
-executable mappings (VM_WRITE, VM_EXEC, or !VM_MAYSHARE), was being
-ignored. As a result the caller of `__rb_map_vma` always returned 0
-even when the mapping had actually failed, allowing it to proceed
-with an invalid VMA.
