Linux 5.10

Quiet and inconspicuous released kernel version 5.10. According to Torvalds himself, the kernel "consists of mostly new drivers interspersed with patches", which is not surprising, since the kernel has received LTS status.

From the new:

• fast_commit support in the Ext4 file system. Now applications will write less metadata to the cache, which will speed up writing! True, it must be explicitly included when creating the file system.

• Additional access settings via the io_uring interface, which allow you to safely share ring resources with child applications.

• System call introduced process_madviseA that allows you to provide the kernel with information about the expected behavior of the target application. A similar system, by the way, is used in Android (the ActivityManagerService daemon).

• Fixed issue 2038 for XFS file system.

and much more.

It is also worth noting that version 5.10.1 was immediately released, canceling two changes, leading to problems in the md and dm raid subsystems. So yes, there are 0-day patches even for the Linux kernel.
