So a bit of an update: I've done the first part of the splitup: the
simple enablement of qrwlock-style rwlocks on x86.
But even that leaves build errors:
include/asm-generic/qrwlock_types.h:14:3: error: conflicting types for
‘arch_rwlock_t’
Which means the base patch is broken:
78e077b0c5ec locking/qrwlock: Introduce qrwlock
I've picked up the other patches (rwsem optimistic spinning and
fallout), and can apply the qwrlock patches once they are fixed and
properly split up.
Thanks,
Ingo
