Hi all, I want to open a device(/dev/sda1, /dev/hda2 etc) in which my file exists. I've used 'stat' system call to get the device id. But now I want the device name from this id(st_dev). How to get that one? Or Do you have any other method to know the device name where my file resides? Thanks Bollywood, fun, friendship, sports and more. You name it, we have it on

This patch series renames "sd_format_disk_name()" to "disk_name_format()" and moves it into block core. So that who needs formatting disk name can use it, instead of duplicating these similar help functions. Ren Mingxin (4): block: add function disk_name_format() into block core scsi: replace sd_format_disk_name() to disk...

virtio-blk set the default queue depth to 64 requests, which was insufficient for high-IOPS devices. Instead set the blk-queue depth to the device's virtqueue depth divided by two (each I/O requires at least two VQ entries).
