Modified files:
sys/kern vfs_bio.c
Log:
- Lock down the buffer cache's infrastructure code. This includes locks on
buf lists, synchronization variables, and atomic ops for the counters.
This change does not remove giant from any code although some pushdown
may be possible.
- In vfs_bio_awrite() don't access buf fields without the buf lock.
