Anyway, moving the counter read into the protected region is a little fiddly because the memory barriers we have in there won't give us the ordering we need. We'll instead need to do something nasty, like create a dependency from the counter read to the read of the seqlock: Maybe the untested crufty hack below, although this will be a nightmare to implement in C.
How is the in kernel ktime_get() correctness guaranteed then? Thanks, tglx _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
