the problem with lost signals in MP kernels.
miod@, kettenis@ ok
|
|
- LK_EXCLUPGRADE is never used.
- LK_REENABLE is never used.
- LK_SETRECURSE is never used. Because of this, the lk_recurselevel
field is always zero, so it can be removed to.
- the spinlock version (and LK_SPIN) is never used, since it was decided
to use different locking structure for MP-safe protection.

defined, and the various ipsec encapsulations only if ipsec is defined.

signal to is the curproc, check if it's SONPROC. That way we'll also
signotify processes on other CPUs. This gives MD code the opportunity
to actually deliver signals to other CPUs faster than the clock
interrupt (in the worst case).
This is a NOP until MD code is fixed.

later when more of it's resources have been allocated and thus
kill(2)ing such a process has more predictable results.

to the m_tag_delete_chain() function.
m_tag_free() and m_tag_unlink() are only used by m_tag_delete() and I see
no need to have these functions around.
m_tag_delete_chain() has a second argument to specifiy a starting point
from where the chain should be deleted. This feature is never used and is
more complex because it is not possible to remove a SLIST element without
doing a list walk. Instead use SLIST_FIRST() and SLIST_REMOVE_HEAD() to
remove all items from the list. OK dhartmei@

from Paul Stoeber with a slightly tweaked diff. NetBSD did the same

should never be referenced outside the context of the process to which
this stack belongs unless we do the PHOLD/PRELE dance. Loads of code
doesn't follow the rules here. Instead of trying to track down all
offenders and fix this hairy situation, it makes much more sense
to not swap kernel stacks.
From art@, tested by many some time ago.

that provides a PPS signal, more precision and less jitter can be expected.
With my test setting (a Garmin GPS 18 LVC hooked up to a i386 machine) I
observed a skew of 0.03 to 0.05 seconds between the tty timestamp and the soft
timestamp.

field unless it's root that's asking. This far, this has been done by
putting a struct statfs on the stack and modifying it.
struct statfs is large. Large things on the stack are bad. Create
copyout_statfs() that copies out a struct statfs to userland, does the
necessary root check and gives userland what it needs withtout wasting
stack space.
