sys/kern vfs_subr.c
Log:
- Solve a race where we could lose a call to VOP_INACTIVE. If vget() waiting
on a lock held the last usecount ref on a vnode and the lock failed we
would not call INACTIVE. Solve this by only holding a holdcnt to prevent
the vnode from disappearing while we wait on vn_lock. Other callers
may now VOP_INACTIVE while we are waiting on the lock, however this race
is acceptable, while losing INACTIVE is not.
