They are always zeroed. * lu.f_tinode and lu.f_tfree are set from the device's super block. */ linux_ustat fills in a structure with the above mention fields. The meaning of f_tinode and f_tfree are explained by the following two statements: lu.f_tfree = stat->f_bfree; lu.f_tinode = stat->f_ffree; In short: given the (u)dev_t, get the FS statistics and return the number of free blocks and inodes of the FS on that device. -- Marcel Moolenaar mail: marcel@cup.hp.com / marcel@FreeBSD.org tel: (408) 447-4222 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
