A large number of commits have been made relating to the following:
VM
a number of minor swap related bugs have been fixed
madvise() enhancements
prepatory 'lastr' field added to vm_map_entry
VN
swap-backed VN now works again
**** major enhancements made to VN device, see new vnconfig man page
NFS
client-side nfs commit rpc now asynchronized (when you are running
nfsiod's), wasn't before.
major performance improvement in server-side nfs commit rpc - full
file fsync replaced with ranged block sync.
SPECFS
A bug related to mmap()ing files backed by disks with sector sizes
larger then 512 bytes fixed.
**** sysctl vfs.enable_userblk_io added, defaults to 1. Setting to 0
disables buffered block device access from usermode, allowing testing
to determine what roadblocks, if any, remain in regards to the removal
of user access to buffered block devices.
Fixes for BOOTP are slated to go in tomorrow.
