[PATCH 1/6] irq/affinity: Assign all online CPUs to vectors

This patch makes sure all online CPUs are assigned to vectors in cases where the nodes don't have the same number of online CPUs. The calculation for how many vectors needs to be assigned should account for the number of CPUs for a particular node on each round of assignment in order to ensure all

Re: [LSF/MM TOPIC][LSF/MM ATTEND] OCSSDs - SMR, Hierarchical Interface, and Vector I/Os

I agree with Damien, but I'd also add that in the future there may very well be some new Zone types added to the ZBC model. So we shouldn't assume that the ZBC model is a fixed one. And who knows? Perhaps T10 standards body will come up with a simpler model for interfacing with

[LSF/MM TOPIC] blk-trace update vs API stability

Hi all, during investigating performance issues I frequently have the need to include the request tag in the scsi tracepoints. While this can be easily done for scsi, including it in block trace output is not that easy due to the interdependency with the blktrace utilities. Also there had been
