Modified files:
sys/kern vfs_subr.c
Log:
sync_vnode() has some messy code about locking in order to deal with
mount fs needing Giant to be held when processing bufobjs.
Use a different subqueue for pending workitems on filesystems requiring
Giant. This simplifies the code notably and also reduces the number of
Giant acquisitions (and the whole processing cost).
