ports. The current bitmap array was too small to hold more than 16
bits and would at some point toggle the context size, which then would
trigger an enumeration fault and cause a fallback to the EHCI
companion controller, if any.

When performing snapshot renames we could deadlock due to the locking
in zvol_rename_minors. In order to avoid this use the same workaround
as zvol_open in zvol_rename_minors.
Add missing zvol_rename_minors to dsl_dataset_promote_sync.
Protect against invalid index into zv_name in zvol_remove_minors.
Replace zvol_remove_minor calls with zvol_remove_minors to ensure
any potential children are also renamed.
Don't fail zvol_create_minors if zvol_create_minor returns EEXIST.
Restore the valid pool check in zfs_ioc_destroy_snaps to ensure we
don't call zvol_remove_minors when zfs_unmount_snap fails.

Add new functions to manipulate these mode & state, instead of calling
kbdd_ioctl() everyhere.
This fixes at least two bugs:
1. The state of the Scroll Lock LED and the state of scroll mode
could be out-of-sync. For instance, if one enables scroll mode on
window #1 and switches to window #2, the LED would remain on, but
the window wouldn't be in scroll mode.
Similarily, when switching between a console and an X.Org
session, the LED states could be inconsistent with the real
state.
2. When exiting from an X.Org session, the user could be unable to
type anything. The workaround was to switch to another console
window and come back.

then LUN 0. If we see LUN 0 disconnected, guess there may be others, and
so REPORT LUNS shall be supported.

usage of a function computing the checksum only over a part of the function.
Therefore introduce in6_cksum_partial() and implement in6_cksum() based
on that.
While there, ensure that the UDPLite packet contains at least enough bytes
to contain the header.

Previous logic was not differentiating disconnected LUNs and absent targets.
That made it to stop scan if LUN 0 was not found for any reason. That made
problematic, for example, using iSCSI targets declaring SPC-2 compliance and
having no LUN 0 configured.
The new logic continues sequential LUN scan if:
-- we have more configured LUNs that need recheck;
-- this LUN is connected and its SCSI version allows more LUNs;
-- this LUN is disconnected, its SCSI version allows more LUNs and we
guess they may be connected (we haven't scanned first 8 LUNs yet or
kern.cam.cam_srch_hi sysctl is set to scan more).

the PAT MSR on guest exit/entry. This workaround was done for a beta release
of VMware Fusion 5 but is no longer needed in later versions.
All Intel CPUs since Nehalem have supported saving and restoring MSR_PAT

Instead requeue mbuf back to IPv4 protocol handler. If there is one extra IP-IP
encapsulation, it will be handled with tunneling interface. And thus proper
interface will be exposed into mbuf's rcvif. Also, tcpdump that listens on tunneling
interface will see packets in both directions.

Sysctl nodes which are dynamically generated for each cloned interface
(net.link.lagg.N.*) have been removed, and use_flowid and flowid_shift
ifconfig(8) parameters have been added instead. Flags and per-interface
statistics counters are displayed in "ifconfig -v".

This is checked for in the zfs_snapshot_004_neg STF/ATF test (currently
still in projects/zfsd rather than head).
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zfs_vfsops.c:
- zfsvfs_create(): Check whether the objset name fits into
statfs.f_mntfromname, and return ENAMETOOLONG if not. Although
the filesystem can be unmounted via the umount(8) command, any
interface that relies on iterating on statfs (e.g. libzfs) will
fail to find the filesystem by its objset name, and thus assume
it's not mounted. This causes "zfs unmount", "zfs destroy",
etc. to fail on these filesystems, whether or not -f is passed.

If an application is willing to accept packets with partial

the minimum coverage it accepts.
