If I interpret the C standard correctly, the storage specifier should be
placed before the inline keyword. While at it, replace __inline by
inline in the files affected.
As C1X is close to being released, there is no need to wrap around a
feature that is already part of C90. Most of these files already use
`const' in different placed as well.
that changed 0.0.0.0/0.0.0.0 prefix to 0.0.0.0/255.0.0.0.
In the r228313 this behavior was fixed, and since dhclient-script
got broken.
I'm not sure this fix is a perfect one, it just changes
dhclient-script to set 0.0.0.0/255.0.0.0 explicitly.

- in destroy_lun_state() assert hold == 1 instead of 0, as it should
receive hold taken by the create_lun_state() or get_lun_statep() before;
- fix hold count leak inside rls_lun_statep() that also fired above assert;
- in destroy_lun_state() use SIM bus number instead of SIM path id for
ISP_GET_PC_ADDR(), as it was before r196008;
- make isp_disable_lun() to set status in CCB;
- make isp_target_mark_aborted() set status into the proper CCB.

This tool only consists of a single C file, so we can simply mark
everything except main() static. This seems to shave off about 8% of the
binary size.

- Use SIOCAIFADDR instead of old rusty SIOCSIFADDR, SIOCSIFBRDADDR
and SIOCSIFNETMASK.
- Use queue(9) instead of hand made stailq.
- Use one socket for all ifioctl() and send/receive operations.
- Use __func__ instead of cut-n-paste in logging and panics.
- Axe some dead or strange code.

lock_success/lock_failure, introduced in r228424, by directly skipping
in dtrace_probe.
This mainly helps in avoiding namespace pollution and thus lockstat.h
dependency by systm.h.
As an added bonus, this also helps in MFC case.

typedef bool. Due to macro expansion it seemed better to use a
typedef for kernel consumers (specifically ofed won't compile
without more changes if a define is used).
- <stdbool.h> should also not re-define bool/true/false if they are
defined by <sys/types.h>. It would probably be a programming error
to define _KERNEL for user-space code, but downstream consumers
like Isilon have already been including <stdbool.h> in kernel
sources, and this protects that usage.
- sizeof(_Bool) is not necessarily the same as sizeof(int), so kernel
modules should be rebuild with this change. Bump __FreeBSD_version.

None of the symbols provided by kbdcontrol.c are used by other source

rtld on 386 and amd64. This adds runtime bits neccessary for the use
of the dispatch functions from the dynamically-linked executables and
shared libraries.
To allow use of external references from the dispatch function, resolution
of the R_MACHINE_IRESOLVE relocations in PLT is postponed until GOT entries
for PLT are prepared, and normal resolution of the GOT entries is finished.
Similar to how it is done by GNU, IRELATIVE relocations are resolved in
advance, instead of normal lazy handling for PLT.
Move the init_pltgot() call before the relocations for the object are
processed.

While there, remove the false optimisation of the colors array. It seems
that changing it to an array of pointers instead of a 16x16 array does
not cause any increase in binary size at all.
Historical behavior of letting other CPUs merily go on is a default for
time being. The new behavior can be switched on via
kern.stop_scheduler_on_panic tunable and sysctl.
Stopping of the CPUs has (at least) the following benefits:
- more of the system state at panic time is preserved intact
- threads and interrupts do not interfere with dumping of the system
state
Only one thread runs uninterrupted after panic if stop_scheduler_on_panic
is set. That thread might call code that is also used in normal context
and that code might use locks to prevent concurrent execution of certain
parts. Those locks might be held by the stopped threads and would never
be released. To work around this issue, it was decided that instead of
explicit checks for panic context, we would rather put those checks
inside the locking primitives.
This change has substantial portions written and re-written by attilio
and kib at various times. Other changes are heavily based on the ideas
and patches submitted by jhb and mdf. bde has provided many insights
into the details and history of the current code.
The new behavior may cause problems for systems that use a USB keyboard
for interfacing with system console. This is because of some unusual
locking patterns in the ukbd code which have to be used because on one
hand ukbd is below syscons, but on the other hand it has to interface
with other usb code that uses regular mutexes/Giant for its concurrency
protection. Dumping to USB-connected disks may also be affected.
