no cryptodev module.) Should probably create a separate cryptodev man
page (or a link to this one) but for now add enough so folks understand
the relationship between the two.

file has been removed, it should be purged from the cache, but it need
not be removed from the directory stack causing corruption; instead,
it will simply be removed once the last references and holds on it
are dropped at the end of the unlink/rmdir system calls, and the
normal !UN_CACHED VOP_INACTIVE() handler for unionfs finishes it off.
This is easily reproduced by repeated "echo >file; rm file" on a
unionfs mount. Strangely, "echo -n >file; rm file" didn't make
it happen.
- Unify the conditional assignments section so that architectural
exclusions come first, sorted, then options and !options, sorted
by the option name, also in directory order, then architecture
specific sections, sorted by the architecture name, with i386
being a traditional exception.

code and simply return EINVAL (which is allowed by the standard) in
all those pthread functions that previously initialized it.
o Refactor the pthread_rwlock_[try]rdlock() and pthread_rwlock_[try]wrlock()
functions. They are now completeley condensed into rwlock_rdlock_common()
and rwlock_wrlock_common(), respectively.
o If the application tries to destroy an rwlock that is currently
held by a thread return EBUSY where it previously went ahead and
freed all resources associated with the lock.
o Refactor _pthread_rwlock_init() to make it look (relatively) sane.
o When obtaining a read lock on an rwlock the check for whether it
would exceed the maximum allowed read locks should happen *before*
we obtain the lock.
o The pthread_rwlock_* functions shall *never* return EINTR, so make
sure to requeue/resuspend the thread if it encounters such an error.
o Make a note that pthread_rwlock_unlock() needs to ensure it holds a
lock on an rwlock it tries to unlock. It will be implemented in a
separate commit because it requires some additional rwlock infrastructure.
According to the Windows DDK header files, KSPIN_LOCK is defined like this:
typedef ULONG_PTR KSPIN_LOCK;
From basetsd.h (SDK, Feb. 2003):
typedef [public] unsigned __int3264 ULONG_PTR, *PULONG_PTR;
typedef unsigned __int64 ULONG_PTR, *PULONG_PTR;
typedef _W64 unsigned long ULONG_PTR, *PULONG_PTR;
The keyword __int3264 specifies an integral type that has the following
properties:
+ It is 32-bit on 32-bit platforms
+ It is 64-bit on 64-bit platforms
+ It is 32-bit on the wire for backward compatibility.
It gets truncated on the sending side and extended appropriately
(signed or unsigned) on the receiving side.
Thus register_t seems the proper mapping onto FreeBSD for spin locks.
the definitions for NDIS_BUS_SPACE_IO and NDIS_BUS_SPACE_MEM logically
belong in hal_var.h. At least, that's my story, and I'm sticking to it.
Also, remove definition of __stdcall from if_ndis.c now that it's pulled
in from pe_var.h.
associated floppy if needed into a static split_openfile() function.
- Use this function in splitfs_open() to open the first chunk rather
than using open() directly. This allows the first chunk to be located
on a different disk than the actual foo.split file.
just libc functions wrappers), and updated text to match reality:
there are three threading libraries in FreeBSD these days.
Removed instructions of how not to build libc_r, it's documented in
the make.conf(5) manpage already.
Removed description of the FreeBSD-specific gcc(1) option, -pthread.
While it's still provided (for backwards compatibility reasons),
its usefulness is questionable.
