FUSE_SYNCFS allows the client to flush the host page cache. v6: - drop ! announce_submounts part for now, only the root inode is synced in this case
v5: - split announce_submounts and ! announce_submounts to separate patches for easier review (but could be squashed together) - track submounts directly in lo_inode structure following the same logic as FUSE_ATTR_SUBMOUNT (i.e. directory with either st_dev or stx_mnt_id different from parent) v4: - based on upstream linux FUSE_SYNCFS - added support for the '-o announce_submounts' case, i.e. client sends a FUSE_SYNCFS request for each submount (identified by its root inode) - adapted the case without '-o announce_submounts' so that syncfs() is no longer called with lo->mutex held v3: - track submounts and do per-submount syncfs() (Vivek) - based on new version of FUSE_SYNCFS (still not upstream) https://listman.redhat.com/archives/virtio-fs/2021-May/msg00025.html v2: - based on new version of FUSE_SYNCFS https://listman.redhat.com/archives/virtio-fs/2021-April/msg00166.html - propagate syncfs() errors to client (Vivek) Greg Kurz (1): virtiofsd: Add basic support for FUSE_SYNCFS request tools/virtiofsd/fuse_lowlevel.c | 11 +++++++ tools/virtiofsd/fuse_lowlevel.h | 13 ++++++++ tools/virtiofsd/passthrough_ll.c | 44 +++++++++++++++++++++++++++ tools/virtiofsd/passthrough_seccomp.c | 1 + 4 files changed, 69 insertions(+) -- 2.34.1 _______________________________________________ Virtio-fs mailing list Virtio-fs@redhat.com https://listman.redhat.com/mailman/listinfo/virtio-fs
