NAME¶
vfs_getvfs —
returns a mount point given its file system
identifier
SYNOPSIS¶
#include
<sys/param.h>
#include
<sys/mount.h>
struct mount *
vfs_getvfs(
fsid_t
*fsid);
DESCRIPTION¶
The
vfs_getvfs() function returns the mount
point structure for a file system given its file system identifier. The file
system ID should have been allocated by calling
vfs_getnewfsid(9); otherwise, it will not be
found.
A major user of
vfs_getvfs() is NFS, which
uses the
fsid as part of file handles in
order to determine the file system a given RPC is for. If
vfs_getvfs() fails to find the mount point
related to
fsid, the file system is
considered stale.
RETURN VALUES¶
If
fsid is found, the mount point for the ID is
returned; otherwise,
NULL is returned.
PSEUDOCODE¶
if ((mp = vfs_getvfs(&fhp->fh_fsid)) == NULL) {
error = ESTALE;
goto out;
}
