The patch titled
fs: introduce write_begin, write_end, and perform_write aops (revoke)
has been removed from the -mm tree. Its filename was
fs-introduce-write_begin-write_end-and-perform_write-aops-revoke.patch
This patch was dropped because an updated version will be merged
------------------------------------------------------
Subject: fs: introduce write_begin, write_end, and perform_write aops (revoke)
From: Nick Piggin <npiggin@xxxxxxx>
These are intended to replace prepare_write and commit_write with more
flexible alternatives that are also able to avoid the buffered write deadlock
problems efficiently (which prepare_write is unable to do).
