Hi,
browsing the sources for some problem I wondered why nvram.c uses a
static spinlock named rtc_lock, hiding the global one.
Regards,
Ulrich

It only does that for the atari, where the driver isnt used by other things

Hmm.. are there different nvram.c drivers? I noticed that SuSE 7.1
loads that driver in i386....
Also doesn't look a lot like Atari:
* This driver allows you to access the contents of the non-volatile
memory in
* the mc146818rtc.h real-time clock. This chip is built into all PCs
and into
* many Atari machines. In the former it's called "CMOS-RAM", in the
latter
* "NVRAM" (NV stands for non-volatile).

Ulrich

The
static spinlock_t
is in the ATARI specific section
