Provide unwind log for bufq sysctls, since (theoretically) bufq might
not be initialized during kernel bootstrap and therefore "permanent"
nodes can be created only with an unwind log.

Replace a large number of link set based sysctl node creations with
calls from subsystem constructors.  Benefits both future kernel
modules and rump.

no change to sysctl nodes on i386/MONOLITHIC & build tested i386/ALL

Add a BUFQ_CANCEL() next to BUFQ_PUT() and BUFQ_GET().

BUFQ_CANCEL(queue, element) removes the specified element previously queued
on the queue. It returns NULL if it was not found on the queue and the
element if it was successfully removed.

Run trough tech-kern and changed name from BUFQ_REVOKE() by suggestion of
Jason Thorpe.

It's not a good idea for device drivers to modify b_flags, as they don't
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.

- Pass the error number and residual count to biodone(), and let it handle
  setting error indicators. Prepare to eliminate B_ERROR.
- Add a flag argument to brelse() to be set into the buf's flags, instead
  of doing it directly. Typically used to set B_INVAL.
- Add a "struct cpu_info *" argument to kthread_create(), to be used to
  create bound threads. Change "bool mpsafe" to "int flags".
- Allow exit of LWPs in the IDL state when (l != curlwp).
- More locking fixes & conversion to the new API.

Revision 1.1 / (download) - annotate - [select for diffs], Sat Oct 15 17:29:26 2005 UTC (6 years, 7 months ago) by yamt
Branch: MAIN

- change the way to specify a bufq strategy.  (by string rather than by number)
- rather than embedding bufq_state in driver softc,
  have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
  from sys/bufq.h to sys/bufq_impl.h.
  (is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c.  (not tested)
