CVS commit: [vmlocking] src/sys/kern

[Andrew Doran <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad
Date:           Thu Nov  1 21:10:15 UTC 2007

Modified Files:
        src/sys/kern [vmlocking]: subr_pool.c

Log Message:
pool_reclaim: acquire kernel_lock if the pool is at IPL_SOFTCLOCK,
SOFTNET or SOFTSERIAL, as mutexes at these levels must still be
spinlocks. It's not yet safe for e.g. ip_intr() to block as this
upsets code calling up from the socket layer. It can find pcbs
sitting half baked.

pool_cache_xcall: go to splvm to prevent kernel_lock from being
taken, for the reason listed above.
