The patch titled
Subject: maccess: rename strncpy_from_unsafe_user to strncpy_from_user_nofault
has been removed from the -mm tree. Its filename was
maccess-rename-strncpy_from_unsafe_user-to-strncpy_from_user_nofault.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Christoph Hellwig <hch@xxxxxx>
Subject: maccess: rename strncpy_from_unsafe_user to strncpy_from_user_nofault
This matches the naming of strncpy_from_user, and also makes it more
clear what the function is supposed to do.
