Subject: 2.6.3 _raw_write_trylock and __down_write_trylock
Date: Mon, 23 Feb 2004 01:15:57 +0000 [thread overview]
Message-ID: <2402.1077498957@kao2.melbourne.sgi.com> (raw)
2.6.3 defines include/asm-ia64/spinlock.h::_raw_write_trylock (both asm
and C versions) and include/asm-ia64/rwsem.h::__down_write_trylock.
The C version of _raw_write_trylock is functionally identical to
__down_write_trylock, but the code is completely different. Why have
two implementations with such radically different code for the same
feature? Why have both a C and asm version of _raw_write_trylock when
the C version will work everywhere?
