Subject: fs/9p: remove unnecessary invalidate_inode_pages2
From: Eric Van Hensbergen <ericvh@xxxxxxxxxx>
commit 350cd9b959757e7c571f45fab29d116d5f67cbff upstream.
There was an invalidate_inode_pages2 added to readonly mmap path
that is unnecessary since that path is only entered when writeback
cache is disabled on mount.
