* fix copying of the extents of the metadata node to the metadatamirror node;
it was not copying all extents.
* fix truncing metadata partition:
* fix endian conversions
* fix information length calculation so its truncated to the right length!
* allow for setting maximum extent length in extent merging. This is needed
since extents in the metadata partition files are only to be in allocation
unit sizes.
* adjust grow and shrink node to set the granularity of the maximum length of
an extent when encountering a metadatafile or metadatamirror file.
Probe "Snake" machines with PDC_MEMMAP and others with PDC_SYSTEM_MAP.
Some PDCs don't tell us about all devices and/or the whole device tree.
Walk each bus to find these unreported devices.
missing at least opaque directory support, but until someone figures
out how that should work on ffs (see PR kern/kern/44383), there's
no point in trying to figure out how it should work here.
erronously entered as thelatin1 file name in the dirhash whereas the matching
routing assumes both UTF-8. This would result in a file being created but not
stat-able since the dirhash couldn't find the entry unless it was remounted.
readings during the sysmon_envsys(9) poll cycle. Some systems (notably,
Asus EeePC) have so badly implemented AML that reading the values via
envstat(8) alone can cause considerable delays.
lower vnode before passing down the VOP_REVOKE(). This way VOP_REVOKE()
on a layered file system always inactivates and closes the lower vnode.
Should finally fix PR kern/43456.
struct fpstate *.
add a new entry point ipi_savefpstate() that is used for this IPI
instead of the plain ipi_savefpstate(). check for %o0 being NULL,
and if so, just return.
add event counters for the savefpstate IPI, and another one for
when it detects the NULL problem.
make the cpu_info struct xmpsg be aligned to a single cache line.
with this change applied (and another minor change in testing) my
SS20 with dual SM75's has survived for 17 hours on build.sh -j5,
and has reported 7 NULL savefps. (the minor change seems to have
a significant effect at reducing this number, but more testing is
needed for it.)
XXX: this is horrible and we really need to find the real problem
XXX: but this should let people use sparc smp again, and fixes
XXX: for the real problem can be tested by seeing if any of the
XXX: savefp IPI null counter becomes non-zero.
Honour this for dependency processing in bsd.dep.mk. Switch i386 and
amd64 assembly to use ISO C90 preprocessor concat and drop the
-traditional-cpp on this platform.
