The patch titled
     Subject: fs: use mapping_set_error instead of opencoded set_bit
has been removed from the -mm tree.  Its filename was
     fs-use-mapping_set_error-instead-of-opencoded-set_bit.patch

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

------------------------------------------------------
From: Michal Hocko <mhocko@xxxxxxxx>
Subject: fs: use mapping_set_error instead of opencoded set_bit

The mapping_set_error() helper sets the correct AS_ flag for the mapping
so there is no reason to open code it.  Use the helper directly.
