.Dd February 21, 2013 .Dt VFS_SET 9 .Os .Sh NAME .Nm VFS_SET .Nd set up loadable file system .Vt vfsconf .Sh SYNOPSIS n sys/param.h n sys/kernel.h n sys/module.h n sys/mount.h .Ft void .Fn VFS_SET "struct vfsops *vfsops" "fsname" "int flags" .Sh DESCRIPTION .Fn VFS_SET creates a .Vt vfsconf structure for the loadable module with the given .Fa vfsops , fsname and .Fa flags , and declares it by calling .Xr DECLARE_MODULE 9 using .Fn vfs_modevent as the event handler.
p Possible values for the .Fa flags argument are: l -hang -width ".Dv VFCF_DELEGADMIN" t Dv VFCF_STATIC File system should be statically available in the kernel. t Dv VFCF_NETWORK Network exportable file system. t Dv VFCF_READONLY Does not support write operations. t Dv VFCF_SYNTHETIC Pseudo file system, data does not represent on-disk files. t Dv VFCF_LOOPBACK Loopback file system layer. t Dv VFCF_UNICODE File names are stored as Unicode. t Dv VFCF_JAIL Can be mounted from within a jail if .Va security.jail.mount_allowed sysctl is set to .Dv 1 . t Dv VFCF_DELEGADMIN Supports delegated administration if .Va vfs.usermount sysctl is set to .Dv 1 . t Dv VFCF_SBDRY When in VFS method, the thread suspension is deferred to the user boundary upon arrival of stop action. .El .Sh PSEUDOCODE d -literal /* * Fill in the fields for which we have special methods. * The others are initially null.
