use these to turn off warnings for most GCC-8 complaints. many
of these are false positives, most of the real bugs are already
commited, or are yet to come.
we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."
configuring default values, retry with a smaller cluster size.
This makes the typical invocation to create a spec conformant EFI boot
partition work out of the box.
otherwise, if DIOCGDISKINFO returns an error != ENXIO getdiskinfo() later
tries to prop_object_release() stack garbage.

returntosingle was defined in multiple places:
- fsck_lfs/main.c
- fsck_ffs/main.c
- fsck_ext2fs/main.c
- fsck/fsutil.c
Keep the fsutil.c definition as the only one.
Detected during the build of telned with Address Sanitizer (MKSANITIZER).
First proposed by jmcneill in 2017 and modified by me.
How to use:
- Set callback function:
ether_set_vlan_cb(struct ethercom *, ether_vlancb_t)
- Callback. This function is called when a vlan is attached/detached to the
parent interface:
int (*ether_vlancb_t)(struct ethercom *ec, uint16_t vlanid, bool set);
- ifconfig(8)
ifconfig ixg0 [-]vlan-hwfilter
Note that ETHERCAP_VLAN_HWFILTER is set by default on ixg(4) because
the PF driver usually enable "all block" filter by default.
Make options to chose alternate label position for systems using MBR
more intuitive. -m now selects mode with MBR, -n selects mode without,
independent of the machine defaults.
gpt_change_ent(). The purpose of the third argument is to specify
whether the entry to be changed is a primary GPT entry or a secondary
GPT entry. It is assumed that a secondary GPT entry will always
follow a corresponding primary entry.
This is in preparation for an upcoming change that will require it.
Make a SMALL dmesg even smaller.
When compiled -DSMALL, dmesg does nothing at all with the kernel
timestamps (it processes no options to be told what would be the
user's desire) so make it truly do (almost) nothing, rather than
some botched partial processing of them.
The "almost" is that a SMALL dmesg will now ignore spaces at the
beginning of each new message line ... those are (vanishingly)
unlikely to occur, as the kernel puts the timestamp (which starts
with '[' there) - fixing this would have meant even more #ifdef's
as the code that ignores that leading space is the only remaining
thing that (in a SMALL) dmesg looks at the value of the "tstamp"
variable, and if we don't keep some use of it, gcc complains...
These changes affect only SMALL dmesg (as installed on boot
floppies, etc) and have no intended effect on the version that's
installed on a normal (full size) running system.
