apparently, for historical reasons, virtually every generic
semaphore.h header file includes the more specific rwsem.h header
file. this is probably a bad thing, since someone who wants only a
generic semaphore shouldn't be forced to include rwsem definitions as
well if they don't need them.

Hallo,
I had some second thoughts about the text patching of DEBUG_RODATA kernels

a separate mapping is a little more gentle. I came up with this patch.
For your review and testing pleasure.
The main quirk is that it
posix_test_lock() returns void, so there is no need to test the return value.

For reference purposes, that position is not acceptable. We _never_ accept the

Seems to be more of an SCC unit allocation library, but OK.

It's an atomic lock shared with userspace. Whatever implementation is
used to do the lock on
arm:
drivers/char/drm/drm_lock.c: In function `drm_lock_take':
drivers/char/drm/drm_lock.c:221: error: implicit declaration of function
`cmpxchg'
You might be able to use atomic_cmpxchg, which _is_ present
on all architectures. Or use a spinlock.
What's that code doing anyway?
