with an ifnet structure (so device_get_softc will get one).
If memory allocation fails in mii_phy_probe, don't just march ahead into
a panic- return ENOMEM.

will be one for struct proc in stable. those drivers needing to have
cross version portability should use d_thread_t instead of inventing
their own means. Non-drivers, and drivers that either only run on
-current or must look under the covers of the struct proc/thread
should must not use this.
As noted in arch@, this minorly violates style(9), but the sys/conf.h
devsw already violates this and all I'm doing is extending the
violation to ease the burdon on device driver writers. It was judged
that this minor violation, which doesn't impact userland or those
people not using it, was preferable to the alternatives (eg #define
proc thread). C does not allow a way to rename or alias structs
easily, so we fall back to using a typedef.
Bump FreeBSD_version to reflect this change (porters guide to be done
in a separate commit).
in vfs_syscalls.c:
if (mp->mnt_stat.f_owner != p->p_ucred->cr_uid &&
(error = suser_td(td)) != 0) {
unwrap_lots_of_stuff();
return (error);
}
to:
if (mp->mnt_stat.f_owner != p->p_ucred->cr_uid) {
error = suser_td(td);
if (error) {
unwrap_lots_of_stuff();
return (error);
}
}
This makes the code more readable when complex clauses are in use,
and minimizes conflicts for large outstanding patchsets modifying the
kernel authorization code (of which I have several), especially where
existing authorization and context code are combined in the same if()
conditional.

- When the video BIOS is called to clear the region (x, y)-(79, 24)
(by scrolling), the slashed region in Fig.1 is cleared. CD() is
supposed to clear the region shown in Fig.2.

- Don't move the cursor during this operation.
- Be consistent about placing spaces around keywords and
operators; don't mix statements like "if(A==B)" and "if (X == Y)",
"return(0)" and "return (-1)", "P=10" and "Q = 0", etc.
- Consitently indent lines. It's not good to indent by 8 columns
in one part of the file, and by 4 columns in the other part.
