Hi Stefan and Sebastien,
I think I should give some background context from my perspective.
For the virtiofsd crash reconnection (recovery) to QEMU, as said by
Stefan, we discussed the possible implementation on the bi-weekly virtio-fs
call. I had also sent an RFC patch to the virtio-fs mail-list
based on it.
3. What about dropping the dirp_map, and integrate the opened directory fds
to fd_map. The virtiofsd-rs implementation only has two maps (inodes and
handles). In the C version, dirp_map may also unnecessary.
All the best,
Jiachen

1, so that the O_DIRECT flags will be retained and host page cache can
