Kernel developer Christian Brauner has sent in the pull request looking to land IDMAPPED mounts functionality as part of the imminent Linux 5.12 merge window. Here is his summary on this big ticket feature that will be part of the next Linux kernel, assuming Linus Torvalds is in agreement with landing this code. IO_uring Will Be Even Faster With Linux 5.12 - Phoronix [3] IO_uring has been one of the greatest Linux kernel innovations in recent times. IO_uring for more efficient asynchronous I/O has continued getting faster and introducing new features over the past two years and for the upcoming Linux 5.12 cycle will be even faster. Linux block maintainer and lead IO_uring developer Jens Axboe has teased that this I/O interface for Linux 5.12 is becoming even faster with a number pegging it at about 10% faster compared to the prior kernel. A 10% speed-up is sizable considering how much faster already IO_uring has evolved on prior kernels for yielding greater performance not only for disk I/O but of growing interest for network I/O and also experimenting with new ioctls being built over IO_uring. Did Linux Kill Commercial Unix? [4] When Dave McKay first used computers, punched paper tape was in vogue, "and he has been programming ever since," according to his biography page at How-To Geek. It adds that "His use of computers pre-dates the birth of the PC and the public release of Unix."
