[PATCH 5/5] xfs: use iomap_dio_rw

Straight switch over to using iomap for direct I/O - we already have the non-COW dio path in write_begin for DAX and files with extent size hints, so nothing to add there. The COW path is ported over from the old get_blocks version and a bit of a mess, but I have some work in progress to make it

[PATCH 4/5] iomap: implement direct I/O

This adds a full fledget direct I/O implementation using the iomap interface. Full fledged in this case means all features are supported: AIO, vectored I/O, any iov_iter type including kernel pointers, bvecs and pipes, support for hole filling and async apending writes. It does not mean

an iomap-based direct I/O implementation V2

Hi all, this series adds a new direct I/O implementation based on the iomap interface, and switches XFS to use it. The first two patches are a resend of my earlier series to remove the XFS iolock. They are needed for the lockdep assert in the new iomap code. The rest implements a new

[PATCH 3/5] fs: make sb_init_dio_done_wq available outside of direct-io.c

We want to use the per-sb completion workqueue from the new iomap direct I/O code. Signed-off-by: Christoph Hellwig --- fs/direct-io.c | 2 +- fs/internal.h | 3 +++ 2 files changed, 4 insertions(+), 1 deletion(-) diff --git a/fs/direct-io.c b/fs/direct-io.c index
