* 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.
__rt_cerror). This enables each library (including libc) the oppurtunity to
make its __cerror hidden and avoid being called via the PLT. No user visible
differences to no need to bump the minor number.
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.
the following work:
mount -t tmpfs -o union tmpfs /
(some caveats are implied, such as if you "mkdir /usr" you're
screwed, but then again you'll get there with "rm -rf /usr" even
without union -- we supply rope)
per discussion with zafer, use case for jibbed
whiteouts and opaque dirs in the upper layer. The sad news is this
simple test fails across the board. It's pretty hard to figure
out how unionfs should work in $fs given that even the simplest
things don't work with ffs.
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.
