shutdown). There are still problems with device access and a PR will be
filed.
- Kill checkalias(). Allow multiple vnodes to reference a single device.
- Don't play dangerous tricks with block vnodes to ensure that only one
vnode can describe a block device. Instead, prohibit concurrent opens of
block devices. As a bonus remove the unreliable code that prevents
multiple file system mounts on the same device. It's no longer needed.
- Track opens by vnode and by device. Issue cdev_close() when the last open
goes away, instead of abusing vnode::v_usecount to tell if the device is
open.
kern.proc, kern.proc2, kern.lwp, and kern.buf.
Define more MIB for kern.buf so that specific buffers can be selected
(only all/all is supported right now), and use a 32/64 bit agnostic
structure for communcating buffer information to userland.
Convert systat to the new kern.buf method.
Clean up the vm.buf* handling a little. There's no actual need to
record the dynamically assigned OIDs, since sysctl_data can tell us
what we're looking at.
Oh, and fix a typo in a comment.
Since the buffer headers do no longer exist as an array in the kernel anymore,
use the new CTL_KERN.KERN_BUF mib to fetch them from kernel space.
Also look at a vnode's specinfo field to properly associate an opened
block device special file with a mounted filesystem.
as in the `vmstat' display mode. The default mode is now `time', not `boot'.
- ANSIfy.
- s@kre\(@vmstat\(@.
- __RCSID() police.
- Tweak inet.icmp display visual a little.
that `systat doesn't handle errors'. Second off, errx should not be used directly, since
the terminal should be cleaned up before bailing. Third off, whatever we do we need
to be consistent.
There, I feel better now.
once per systat invocation, not each time we switch to the bufcache
display.
Fixes core dump noted by Andy Doran when switching back and forth to
bufcache display.
