(and pollts(2)) are similar to sigsuspend(2) in that they temporarily change
the process signal mask and wait for signal delivery. Factor out and share the
code that does this.
rename "UVMHIST" option to enable the uvm histories.
TODO:
- make UVMHIST properly depend upon KERNHIST
- enable dynamic registration of histories. this is mostly just
allocating something in a bitmap, and is only for viewing multiple
histories in a merged form.
tested on amd64 and sparc64.
to prevent a crash when attempting rename("/", "foo"). This is not really
what I want going forward and it may cause e.g. rmdir("blah/") to fail, so
if it causes trouble for anyone back it out. The right fix is going to have
to wait until the qemu/tcp_vtw problems I ran into last night get sorted out.
- Prevent sys/resourcevar.h from inclusion in userland.
- sys_{set,get}priority: use id_t for 'who', not int.
- Make donice() routine static.
- Remove trailing spaces, KNF.
- Add pcu_ops_t::pcu_state_release() operation for PCU_RELEASE case.
- Add pcu_switchpoint() to perform release operation on context switch.
- Sprinkle const, misc. Also, sync MIPS with changes.
Per discussions with matt@.
already prevented). File systems are no longer responsible to check this.
Clean up and add asserts (note that dvp == vp cannot happen in vop_link).

- Simplify message queue descriptor unlinking and closure operations.
- Update proc_t::p_mqueue_cnt atomically. Inherit it on fork().
- Use separate allocation for the name of message queue.
reversing the sense of the associated test and using the big block I
moved a couple versions back (and didn't reindent on purpose) as the
body of the if statement.
There are now no gotos in namei_oneroot, only normal loop logic.
now be changed to a loop break and another null test and goto outside
the loop. In neither of the other two cases for exiting the loop can
foundobj be null.
has an unconditional loop break at the end this can be done safely,
now that the other loop break has been patched out.
Add a spurious set of braces to preserve the indent for the moment.
continue.
This runs the "are we mounted?" test on every directory instead of
only sometimes; however, it's not exactly an expensive test (null
pointer check) and the prior logic wasn't exactly sensible -- it
checked at the beginning and after following a symlink but, for some
reason, not after crossing a mount point.
