Subject: [PATCH v4 0/8] fuse,virtiofs: support per-file DAX
Date: Tue, 17 Aug 2021 10:22:12 +0800 [thread overview]
Message-ID: <20210817022220.17574-1-jefflexu@linux.alibaba.com> (raw)
This patchset adds support of per-file DAX for virtiofs, which is
inspired by Ira Weiny's work on ext4[1] and xfs[2].
Any comment is welcome.
[1] commit 9cb20f94afcd ("fs/ext4: Make DAX mount option a tri-state")
[2] commit 02beb2686ff9 ("fs/xfs: Make DAX mount option a tri-state")
changes since v3:
- bug fix (patch 6): s/"IS_DAX(inode) != newdax"/"!!IS_DAX(inode) != newdax"
- during FUSE_INIT, advertise capability for per-file DAX only when
mounted as "-o dax=inode" (patch 4)
changes since v2:
- modify fuse_show_options() accordingly to make it compatible with
new tri-state mount option (patch 2)
- extract FUSE protocol changes into one seperate patch (patch 3)
- FUSE server/client need to negotiate if they support per-file DAX
(patch 4)
- extract DONT_CACHE logic into patch 6/7
v3: https://www.spinics.net/lists/linux-fsdevel/msg200852.html
v2: https://www.spinics.net/lists/linux-fsdevel/msg199584.html
v1: https://www.spinics.net/lists/linux-virtualization/msg51008.html
