compatibility with the different environment conventions" (man page).
With the standards, we don't have them different anymore and
IEEE Std 1003.1-2001 says that
"The values that the environment variables may be assigned are not
restricted except that they are considered to end with a null byte"
Issue 6 (also IEEE Std 1003.1-2001) in following areas:
args, return, errors.
Putenv still needs rewriting because specs explicitly says that
altering passed string later should change the environment (currently we
copy the string so can't provide that).
to override weak symbols exported by libc, so by definition these two
are using the same symbol version names.
Reflect the reality by referring to libc's Versions.def directly.
- edsc(4) added
- pmcstat(4) -c and -t flags, defaults changed
- rpcbind -h and -6 flags
Modified release notes:
- Moved pmcstat information from kernel to userland section
- MSI-X supported as well, remove ref to pci(4) manpage, which is
different from the kernel's PCI code
- rpc.lockd/rpc.statd entry moved to the right place
were never freed, but the big ring was freed twice.
-Don't supply rx hw csums for frames which are padded beyond the
length specified in the ip header. If the padding is non-zero,
the hw csum will be incorrect for such frames.

- Allow the "-t" option to take a regular expression naming command
line processes to attach process PMCs to.
- Update the manual page and add an example showing the use of the
new functionality.
- Update the (c) year on the affected source files.
non-mapped data as possible at once and not page-by-page. Which this change we
combain I/Os, but also saves many VM_OBJECT_UNLOCK()/VM_OBJECT_LOCK()
operations.
Simple 'fsx -l 33554432 -o 524288 -N 10000 /tank/fsx' test shows ~23%
performance increase.
This workaround the problem in Parallels/VMWare where the emulated drivers are
slower, especially with ATA_FLUSHCACHE. The problem appears much more
frequently with ZFS which use it a lot more.

- vm_page_undirty() is enough (instead of vm_page_set_validclean()), but it has
to be called before we write the data in case someone makes page dirty after
our write, but before our vm_page_undirty() call.
- Always dmu_write, not matter if uiomove() succeeded, because it could
partially be ok and we would lose some changes.
All good ideas from: ups
In dounmount(), before or while vn_lock(coveredvp) is called, coveredvp
vnode may be VI_DOOMED due to one of the following:
- other thread finished unmount and vput()ed it, and vnode was chosen
for recycling, while vn_lock() slept;
- forced unmount of the coveredvp->v_mount fs.
In the first case, next check for changed v_mountedhere or mnt_gen counter
would be successfull. In the second case, the unmount shall be allowed.

- Fix for a bug where a close would not wait for all (directio)
dirty buffers to drain. The nfsnode was not marked NMODIFIED
when there were directio dirtied buffers pending, causing this.
- No reason to vhold/vrele the vp when enqueueing DirectIO requests
for the nfsiods. The vnode can't really go way since the close
has to wait for these requests to drain.
