VFS_SET(9) BSD Kernel Developer's Manual VFS_SET(9) NAME VFS_SET -- set up loadable file system vfsconf SYNOPSIS #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 ker- nel. 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 allow.mount and allow.mount._fsname_ jail parameters are set. VFCF_DELEGADMIN Supports delegated administration if vfs.usermount sysctl is set to 1. VFCF_SBDRY When in VFS method, the thread suspension is deferred to the user boundary upon arrival of stop action.

This tells vfs to change them to * pointers to vfs_std* functions during file system registration. */ static struct vfsops myfs_vfsops = { .vfs_mount = myfs_mount, .vfs_root = myfs_root, .vfs_statfs = myfs_statfs, .vfs_unmount = myfs_unmount, }; VFS_SET(myfs_vfsops, myfs, 0); SEE ALSO jail(2), jail(8), DECLARE_MODULE(9), vfs_modevent(9), vfsconf(9) AUTHORS This manual page was written by Chad David <davidc@acns.ab.ca>.
