The patch titled
kill do_generic_mapping_read
has been removed from the -mm tree. Its filename was
kill-do_generic_mapping_read.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: kill do_generic_mapping_read
From: Christoph Hellwig <hch@xxxxxx>
do_generic_mapping_read was used by gfs2 for internals reads, but this use
of the interface was rather suboptimal (as was the whole interface) and has
been replaced by an internal helper now. This patch kills
do_generic_mapping_read and surrounding damage in preparation of additional
cleanups for the buffered read path.
