The sole purpose of this change is to make sure that sizeof produces
"canonical" sizes for these structures. This is to avoid triggering
bugs in the BIOSes that properly handle only the canonical values of
input length provided to INT 13h AH=48h.
The canonical sizes are: 30 for v2, 66 for v3, etc.
Buggy BIOS code probably looks like:
if (input_length > 30) { /* > v2 */
assume that input length is 66 /* assume v3 or later */
}
This should fix boot problems at least on Supermicro X8DT6 and possibly
on P410i Smart Array Controller (as found in e.g. HP DL360 G7).

crash. When truncating a file that never made it to disk we use the
canceled allocation dependencies to hold the journal records until
the truncation completes. Previously allocdirect dependencies on
the id_bufwait list were not considered and their journal space
could expire before the bitmaps were written. Cancel them and attach
them to the freeblks as we do for other allocdirects.
- Add KTR traces that were used to debug this problem.
- When adding jsegdeps, always use jwork_insert() so we don't have more
than one segdep on a given jwork list.

than we're claiming it should still be considered an exact match. This
would previously leak frags that had been extended.
- If there is a sequence number problem in the journal print the sequence
numbers we've seen so far for debugging.
- Clean up the block mask related debuging printfs. Some are redundant.

designator to select a process which is waited for. The system call
optionally returns siginfo_t which would be otherwise provided to
SIGCHLD handler, as well as extended structure accounting for child
and cumulative grandchild resource usage.
Allow to get the current rusage information for non-exited processes
as well, similar to Solaris.
The explicit WEXITED flag is required to wait for exited processes,
allowing for more fine-grained control of the events the waiter is
interested in.
Fix the handling of siginfo for WNOWAIT option for all wait*(2)
family, by not removing the queued signal state.

- In sys/ofed/drivers/infiniband/core/cma.c, an enum struct member is
interpreted as an int, so cast it to an int.
- In sys/ofed/drivers/infiniband/core/ud_header.c, initialize the
packet_length variable in ib_ud_header_init(), to prevent undefined
behaviour.
- In sys/ofed/drivers/infiniband/ulp/sdp/sdp_rx.c, call rdma_notify()
with the correct enum type and value.
- In sys/ofed/include/linux/pci.h, change the PCI_DEVICE and PCI_VDEVICE
macros to use C99 struct initializers, so additional members can be
overridden.
