Description

This Epic will keep track of various tasks to improve virtiofsd robustness.

In no particular order:

• CI/CD Improvements
• Check how our ops affects threads
• Concentrate/get rid of unsafe blocks
• Check functions safety (API mostly)
• I/O safety (OwnedFd/BorrowedFd)
• FD table isolation
• fsync before migration
• Before migration, force the kernel to FORGET unused (not opened) cached fuse_inodes
