As an aside, I expect to use it for all sorts of things (like backups: bup likes to reread all data sometimes, and I don't want to blow the bcache when it does), but in particular I plan to use it for things I know will be using large volumes of data for the last time before destruction -- things like manual and automated 'git gc', where I know that preserving the old packfiles in the bcache is a total waste of time and where the packfiles being read in only to be deleted may be very large. (I'm running in writearound mode, so the lack of useful ioprio for writeback is not a problem for me, and I can cope with the lack of ioprio for NFS reads, though I vaguely wish there was a way to propagate some sort of please-don't-cache-this hint across that channel too!) -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
