H A D | atomic.h | diff 48796 Tue Jul 13 01:32:17 MDT 1999 alc Changed the implementation of the primitives to guarantee atomicity with respect to interrupts on UP systems. (The upgrade from gcc 2.7.x to egcs 1.1.2 produced at least one non-atomic code sequence in swap_pager_getpages.) In addition, the primitives are now SMP-safe, but only on SMPs. (For portability between SMPs and UPs, modules are compiled with the SMP-safe versions.) Submitted by: dillon and myself Reviewed by: bde |
