Hi all,
this series cleans up some of the generic write helper calling
conventions and the page cache writeback / invalidation for
direct I/O. This is a spinoff from the no-bufferhead kernel
project, for which we'll want to an use iomap based buffered
write path in the block layer.
Changes since v1:
- remove current->backing_dev_info entirely
- fix the pos/end calculation in direct_write_fallback
- rename kiocb_invalidate_post_write to
kiocb_invalidate_post_direct_write
- typo fixes
