Hi all, This series creates a new "kernel" mount option that signals to the fuse2fs driver that it's being used as a containerizable replacement for the kernel driver. This has the effect of delegating quite a lot of decisionmaking to the kernel, and opening access to users other than whoever's running the fuse2fs server. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. Comments and questions are, as always, welcome. e2fsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/e2fsprogs.git/log/?h=fuse2fs-kernel --- Commits in this patchset: * fuse2fs: add dummy acl/user_xattr mount options * fuse2fs: set fuse subtype via argv[0] if possible * fuse2fs: make "ro" behavior consistent with the kernel --- misc/fuse2fs.c | 56 ++++++++++++++++++++++++++++++++++++++------------------ 1 file changed, 38 insertions(+), 18 deletions(-)
