sys/sys : pool.h
Log message:
pool(9): remove ticks
Change the pool(9) timeouts to use the system uptime instead of ticks.
- Change the timeouts from variables to macros so we can use
SEC_TO_NSEC(). This means these timeouts are no longer patchable
via ddb(4). dlg@ does not think this will be a problem, as the
timeout intervals have not changed in years.
- Use low-res time to keep things fast. Add a local copy of
getnsecuptime() to subr_pool.c to keep the diff small. We will need
to move getnsecuptime() into kern_tc.c and document it later if we
ever have other users elsewhere in the kernel.
- Rename ph_tick -> ph_timestamp and pr_cache_tick -> pr_cache_timestamp.
Prompted by tedu@ some time ago, but the effort stalled (may have been
my fault). Input from kettenis@ and dlg@.
Special thanks to mpi@ for help with struct shuffling. This change
does not increase the size of struct pool_page_header or struct pool.
ok dlg@ mpi@
