EINVAL, that error code is ignored, leaving whatever other meaningful
error code that might have previously been returned intact. Stand-alone
file system implementations return EINVAL typically when the file system
is not recognized (i.e. cd9660_open on a UFS file system, ufs_open on a
cd9660 file system, etc.). This meant that if you had multiple file
systems in a file system switch, the first returned ENOENT (because
it recognized the file system type, but the file wasn't there) and
the second returned EINVAL (because it didn't recognize the file system
type), errno would be set to EINVAL. Now it'll be set to ENOENT.
It would probably make sense to have file systems return a special
error code to indicate "this file system is unrecognized," which
could then be special-cased, but that's a fair bit more invasive.
- fix the parser so that non-compliant isapnp devices work, and we
give up when there are too many errors (some on-board pnp sound/atapi/game
soundblaster compatible card). reported by chuck cranor
- fix the parser so that configuration tags that come after the
end-dependencies tag or before the begin-dependencies tag are merged
in properly (gravis ultrasound). reported by gary duzan
We now build a tree of card -> logical-dev -> conf, and in the end we
convert it to a list of conf...
- if aal5 frame has a CRC error then the length field in the aal5 trailer
may not be valid, so we can not use it [and we must dump the frame]

set -- ""; echo ${1:-wwww} works.
- when expanding arithmetic, discard previous ifs recorded regions, since we
are doing our own scanning. x=ab; echo $((${#x}+1)) now works.
- in ${var#word} fix two bugs:
* if there was an exact match, there was an off-by-one bug in the
comparison of the words. x=abcd; echo ${x#abcd}
* if there was no match, the stack region was not adjusted and the rest
of the word was getting written in the wrong place. x=123; echo ${x#abc}X
these, we should define all, because there might be code elsewhere
that needs them (in this case, libsa). Add comments that describe the
data types that the isonum_* functions access.
about ISO9660 file system structure), and cd9660_extern.h (which now
contains the definitions and data structures used by the kernel).
There's lots of other stuff scattered around this code that should go
into cd9660_extern.h, but doesn't need to right now. This changed patterned
on ffs, which has 'fs.h' which describes the FS structure, and ffs_extern.h
for kernel-internals gunk. Now libsa can include iso.h without the nasty
hack that was there before.
Also, clean up the isonum_* definitions so that the #ifdefs aren't
impossibly spread apart. (Now the #ifdefs are _in_ the functions. This
leads to #ifdefs that are only a few lines long, rather than a few _pages_
long, as well as a reduction of duplication of function headers, etc.)
Note that isonum_7{21,22,31,32} are currently missing.
