Hm this is the same as the other "2.6.15-rc5-rt4 fails to compile". rwsem.c
should not even be in there.
Is this a Kconfig bug then?
config RWSEM_GENERIC_SPINLOCK
bool
depends on M386 || PREEMPT_RT
default y
config RWSEM_XCHGADD_ALGORITHM
bool
default y if !RWSEM_GENERIC_SPINLOCK
PREEMPT_RT=y, but the .config file has RWSEM_XCHGADD_ALGORITHM=y!
Maybe the "default y if !RWSEM..." is not evaluated and we need something
like this?
default y if !RWSEM_GENERIC_SPINLOCK
default n if RWSEM_GENERIC_SPINLOCK
