John Dyson 6b195d32a1 Fix a problem with the VN device. Specifically, the VN device can ... cause a problem of spiraling death due to buffer resource limitations. The vfs_bio code in general had little ability to handle buffer resource management, and now it does. Also, there are a lot more knobs for tuning the vfs_bio code now. The knobs came free because of the need that there always be some immediately available buffers (non-delayed or locked) for use. Note that the buffer cache code is much less likely to get bogged down with lots of delayed writes, even more so than before.		1997-06-15 17:56:53 +00:00
