Same here.  Please have one patch that actually adds useful atomic write
support to the block layer.  That doesn't include fs stuff like
IOCB_ATOMIC or the block file operation support, but to have a reviewable
chunk I'd really like to see the full block-layer support for the limits,
enforcing them, the merge prevention in a single commit with an extensive
commit log explaining the semantics.  That allows a useful review without
looking at the full tree, and also will help with people reading history
in the future.
