Subject: [PATCH v3 0/8] fuse,virtiofs: support per-file DAX
Date: Wed, 4 Aug 2021 15:06:45 +0800 [thread overview]
Message-ID: <20210804070653.118123-1-jefflexu@linux.alibaba.com> (raw)
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
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.
