Subject[PATCH v4 0/5] virtiofs: propagate sync() to file server
Date
This was a single patch until v3. Some preliminary cleanups were

introduced for submounts in this v4.



This can be tested with a custom virtiofsd implementing FUSE_SYNCFS, here:



https://gitlab.com/gkurz/qemu/-/tree/fuse-sync



v4: - submount fixes

- set nodeid of the superblock in the request (Miklos)



v3: - just keep a 64-bit padding field in the arg struct (Vivek)



v2: - clarify compatibility with older servers in changelog (Vivek)

- ignore the wait == 0 case (Miklos)

- 64-bit aligned argument structure (Vivek, Miklos)



Greg Kurz (5):

fuse: Fix leak in fuse_dentry_automount() error path

fuse: Call vfs_get_tree() for submounts

fuse: Make fuse_fill_super_submount() static

virtiofs: Skip submounts in sget_fc()

virtiofs: propagate sync() to file server
