NAME¶
VFS_SET — set up loadable file system vfsconfSYNOPSIS¶
#include <sys/param.h>#include <sys/kernel.h>
#include <sys/module.h>
#include <sys/mount.h> void
VFS_SET(struct vfsops *vfsops, fsname, int flags);
DESCRIPTION¶
VFS_SET() creates a vfsconf structure for the loadable module with the given vfsops, fsname and flags, and declares it by calling DECLARE_MODULE(9) using vfs_modevent() as the event handler. Possible values for the flags argument are:VFCF_STATIC
- File system should be statically available in the kernel.
VFCF_NETWORK
- Network exportable file system.
VFCF_READONLY
- Does not support write operations.
VFCF_SYNTHETIC
- Pseudo file system, data does not represent on-disk files.
VFCF_LOOPBACK
- Loopback file system layer.
VFCF_UNICODE
- File names are stored as Unicode.
VFCF_JAIL
- Can be mounted from within a
jail if security.jail.mount_allowed sysctl is set to
1
. VFCF_DELEGADMIN
- Supports delegated
administration if vfs.usermount sysctl is set to
1
.
PSEUDOCODE¶
/* * fill in the ones we use, and use the vfs_std for the rest. */ static struct vfsops myfs_vfsops = { myfs_mount, vfs_stdstart, myfs_unmount, myfs_root, vfs_stdquotactl, myfs_statfs, vfs_stdsync, vfs_stdvget, vfs_stdfhtovp, vfs_stdcheckexp, vfs_stdvptofh, vfs_stdinit, vfs_stduninit, vfs_stdextattrctl, }; VFS_SET(myfs_vfsops, skelfs, 0);
