Subject: [PATCH -mm 10/10][RFC] aio: convert file aio to file_endio_t
Convert the file_operation function prototypes to the new file_endio_t
approach. This doesn't change much code in the file systems, just some
straightforward conversions in mm/filemap.c. It also fixes up callers of
the f_op interface, including some code restructuring in fs/read_write.c,
fs/compat.c, and fs/aio.c. Other than that and removing ntfs's redundant
readv_writev thing, this should be pure callsite fixes.
