For non-ea UFS2 file system, fail mounts that request ACLs rather than
letting the mount succeed only to reject all ACL operations later.
Also fix the messages about the on-disk fs flags conflicting with
the mount options for which type of ACLs to use, and about requesting
both types of ACLs.
the swap/drum block device was never intended to allow user opens,
but when the internal VOP_OPEN() in uvm_swap_init() was added
back in rev 1.135, the d_open method was changed from always-fail
to always-succeed in order to allow the new initial internal open.
this had the side effect of incorrectly allowing user opens too.
fix this by replacing the swap_bdevsw d_open with one that succeeds
for the first call but fails for all subsequent calls.

This version of the file, and the generator script, come from
OpenBSD. The script was written by Andrew Fresh.
The file covers the encodings from Unicode 13.0.0, based on the files
distributed with perl 5.32.1.
As best I can tell, the rest of what mandoc -Wall complains about is
incorrect (it could probably be avoided by adding more markup, but
there doesn't seem to be any point).
tail chain is not necessarily the same as the last mbuf of the initial chain.
Always set "slp->ns_rawend" to the last mbuf of the tail chain to prevent
mbuf leaks and corruption.
the number of bytes to add - for multibyte characters n will be > 1.
Fix __slk_draw to pass in the actual length of the label instead of
the default label length because wide characters may make the
actual string length longer than the slk display length.
These files are not used anymore. Files for compat code are listed in
sys/comapt/common/files.common and sys/modules/compat_xxx/Makefile.
OK'd by riastradh@ and pgoyette@.
remove the mention of "fslevel 5" because no such thing exists.
the whole "fs level" concept really only applies to UFS1, so don't print
the line with the level number and details for UFS2 file systems at all.
try to clarify this in the manpage as well.

- Changed sampling buffer switching frequency (which is the frequency of tprof_worker()
calls and also the maximum block time of read(2) of /dev/tprof) from 1sec to 125ms.
This improve tprof top responsiveness.
- The maximum number of sampling buffers is now adjusted according to the number of CPUs.
Previously it was fixed at 100 and was insufficient if ncpu was greater than this.
The maximum number of samples per second per CPU is calculated by
"TPROF_MAX_SAMPLES_PER_BUF * (HZ of tprof_worker)".
Therefore, currently, 10000 * (1000/125) = 80000 maximum samplings per CPU.
The actual value will vary slightly from this due to tprof_worker and read(2) timing.
This value may need to be adjusted more in the future.
