I am most grateful to you.
I add flag like as follows.
static struct cdevsw mypci_cdevsw = {
.d_version = D_VERSION,
.d_flags = D_NEEDGIANT|D_TRACKCLOSE,
^^^^^^^^^^^^^^
.d_open = mypci_open,
.d_close = mypci_close,
.d_read = mypci_read,
.d_write = mypci_write,
.d_ioctl = mypci_ioctl,
.d_name = "mypci",
};
Then the program runs as I expected.
Close routine has called!!!
Thanks a lot!!!!!
