side effect of that change caused headers to not be sent if a 0 byte
file was passed to sendfile. This change fixes that behavior, allowing
sendfile to send out the headers even with a 0 byte file again.

equal to the process ID) is still present when we dump a core. It
already may have been destroyed. In that case we would end up
dereferencing a NULL pointer, so specifically test for that as well.

Remove spurious whitespace, add indent protection, fix punctuation,
remove initialization of static variables to zero, put wakeup_ctr
and wakeup_needed in the correct order. (reported by bde)
This doesn't fix all the style bugs I introduced, but the remaining
style bugs make it easier for me to understand what I did here.

powerstate functionality, the ACPI _PSx methods are executed and ACPI
PowerResources are switched on and off via the acpi_pwr_switch_consumer()

the NOKERNINFO flag only marginally de-clutters the output and
has a number of unwanted side effects:
o The kernel info might be what you want to see
o ^T is left non-functional if ping is killed non-cleanly
o "ping -q foo &" gets suspended on tty output

before calling BUS_GET_RESOURCE_LIST(). Previously, the list head would
only be initialized if BUS_GET_RESOURCE_LIST() succeeded; it needs to
be initialized unconditionally so that the list cleanup code won't
trip over potential stack garbage.
we convert ip_len into a network byte order; in_delayed_cksum() still
expects it in host byte order.
The symtom was the ``in_cksum_skip: out of data by %d'' complaints
from the kernel.
To add to the previous commit log. These fixes make tcpdump(1) happy
by not complaining about UDP/TCP checksum being bad for looped back
IP multicast when multicast router is deactivated.

* ACL storage is no longer erased before a group of entries are added.
* ACL text creation no longer tries to skip over non-existent text.
* UTF8 encoder no longer blows up on invalid wide characters.
* Fixed ACL state management for default ACLs.
Also, publicize function for obtaining text-format ACL in various
formats. The interface is now extensible through a "flags" argument
that allows you to select a variant format.
callout_stop(), except that if the callout being stopped is currently
in progress, it blocks attempts to reset the callout and waits until the
callout is completed before it returns.
This makes it possible to clean up callout-using code safely, e.g.,
without potentially freeing memory which is still being used by a callout.

is a separate of the various modes of operation date has, as well as
sectioning off the two deprecated options for settimeofday(tz) that
don't even apply to actual operation of date as such, anyway.
