Subject: reflink direct I/O improvements V3
Date: Mon, 6 Feb 2017 08:47:34 +0100 [thread overview]
Message-ID: <20170206074738.13978-1-hch@lst.de> (raw)
This series improves the reflink direct I/O path, by avoiding a pointless
detour through delayed allocations and doing the allocations directly
from the iomap code.
Changes since V2:
- handle the new scheme to use unwritten extents for preallocation
properly
- fix up tracing for bounced dio writes
Changes since V1:
- align the alignment code with the regular direct I/O path
- rebase on top the patches from Darrick to use unwritten extents
in the direct I/O COW path
