hi, all
(thanx for the links to the books)
i have added few handlers to
my_vnops.c file (that originally was null_vnops.c of "nullfs")
and (with intention to involve my handlers into execution flow)
i have extended struct vop_ops (last 4 lines):
struct vop_ops my_vnode_vops = {
.vop_nresolve = null_nresolve,
.vop_ncreate = null_ncreate,
.vop_nmkdir = null_nmkdir,
.vop_nmknod = null_nmknod,
.vop_nlink = null_nlink,
.vop_nsymlink = null_nsymlink,
.vop_nwhiteout = null_nwhiteout,
.vop_nremove = null_nremove,
.vop_nrmdir = null_nrmdir,
.vop_nrename = null_nrename,
.vop_mountctl = null_mountctl,
.vop_open = my_open,
.vop_read = my_read,
.vop_write = my_write,
.vop_access = my_access
};
then i have noticed that my_*() handlers were never called no matter what operations i perform on my test subject.
the question is:
(1) What am i doing wrong?
(2) Is there any official description what is a purpose of each handler in struct vop_ops and WHEN it shall be called?
