IDMAPPED Mounts Aim For Linux 5.12 - Many New Use-Cases From Containers To -Homed - Phoronix[2]

Ahead of the Linux 5.12 merge window expected to open at end of day tomorrow, assuming Linux 5.11 is out on schedule, there is already a pending pull request with a big feature addition: IDMAPPED mounts.

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 , assuming 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 being built over IO_uring.
