by the second argument to be locked. We now use the thread ucred reference
for the credential checks in p_can*() as a result. p_canfoo() should now
no longer need Giant.
IFS had its fingers deep in the belly of the UFS/FFS split. IFS
will be reimplemented by the maintainer at a later date.

ext2fs, inode numbers start at 1, so the maximum valid inode number
is (s_inodes_per_group * s_groups_count), not one less. This is
just a minimal change to avoid unnecessary panics and errors; some
other related bugs that Bruce Evans mentioned to me are not addressed.

yields incorrect behaviour. The hardwiring was present in the very
first commit that implemented msgrcv() (revision 1.4) and hasn't been
changed since. The native implementation was complete at that time,
so there doesn't seem to be a reason for the hardwiring from a
technical point of view.

regardless of if they are signed or unsigned since it is easier to work
with sign-extended values. Thus, remove the disabled zapnot to
zero-extend the sign-extended value we read from *p in atomic_cmpset_32()
since the cmpval we are comparing against should already be
sign-extended.
- To ensure that the compiler knows to sign-extend the upper 32 bits of
cmpval rather than leaving garbage in there, cast the appropriately in
the constraints section.

shared code and converting all ufs references. Originally it may
have made sense to share common features between the two filesystems,
but recently it has only caused problems, the UFS2 work being the
final straw.
All UFS_* indirect calls are now direct calls to ext2_* functions,
and ext2fs-specific mount and inode structures have been introduced.

Avoid one place where I'm at splnet across a call to copyout. Leave
one in place to give bde something to complain about :-). Actaully,
I'll fix it in a subsequent commit.

allow recovery from transmission lockups which occur in the middle
of the descriptor list, rather than just at the beginning.
For some unknown reason, Rhine II chips have a tendency to stop
transmitting while under heavy load, possibly due to collisions.
Whether this behavior is due to a hardware bug or a driver glitch
is unknown as of now.
In either case, this change allows the driver to gracefully recover
from such situations.
Special thanks go to The Anarcat <anarcat@anarcat.dyndns.org>, who
bugged me into looking at this and to
Dominic Marks <dominic_marks@btinternet.com>, who performed a great
deal of testing to help characterize this problem.

inter-process signalling ceased to preserve and return that value,
instead always returning EPERM. This meant that it was possible
to "probe" the pid space for processes that were not otherwise
visible. This change reverts that reversion.
