I thought we had such a > mechanism? While Xen is the primary user, it is a misnomer to call it xen-bitops. These are simply always locked, hence the sync-bitops name. Also, there's a use of sync_cmpxchg, and cmpxchg is not in bitops.h. As for the mechanism, it is manual. Arch specific header includes asm-generic one.
