NAME
       vfs_permission - check for access rights to a given path


SYNOPSIS
       int vfs_permission  (struct nameidata * nd, int mask);


ARGUMENTS
       nd     lookup result that describes the path

       mask   right to check for (MAY_READ, MAY_WRITE, MAY_EXEC)


DESCRIPTION
       Used  to  check  for  read/write/execute  permissions on a path. We use
       ‘‘fsuid’’ for this, letting us set arbitrary permissions for filesystem
       access  without  changing  the ‘‘normal’’ uids which are used for other
       things.
