Let's take one step back here. I agree with Josef that sending one single flush is perfectly fine for all usual cases. The issue that was brought up last time we had this discussion was that some (I think mostly theoretical) backends could not be coherent and this would be an issue. So maybe the right way is to simply not support the current odd flush defintion in the kernel then and require a new properly defined flush version instead. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Nbd-general mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/nbd-general
