[merged] maccess-rename-strncpy_from_unsafe_strict-to-strncpy_from_kernel_nofault.patch removed from -mm tree

[akpm]

The patch titled
     Subject: maccess: rename strncpy_from_unsafe_strict to strncpy_from_kernel_nofault
has been removed from the -mm tree.  Its filename was
     maccess-rename-strncpy_from_unsafe_strict-to-strncpy_from_kernel_nofault.patch

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

------------------------------------------------------
From: Christoph Hellwig <hch@lst.de>
Subject: maccess: rename strncpy_from_unsafe_strict to strncpy_from_kernel_nofault

This matches the naming of strncpy_from_user_nofault, and also makes it
more clear what the function is supposed to do.
