Recall that the previously proposed asynchronous input\/output mechanism 'aio' did not support buffered I\/O, could only operate in O_DIRECT mode (without buffering and bypassing the cache), faced issues with blocking due to waiting for metadata availability, and demonstrated high overheads from copying data in memory.\n<p>Within the API<br \/>\nio_uring, developers attempted to address the shortcomings of the old aio interface.

Now such monitoring can be effectively performed through fanotify;<\/p>\n<li class=\"l\"> In the Btrfs file system <noindex><a rel=\"nofollow\" href=\"https:\/\/git.kernel.org\/pub\/scm\/linux\/kernel\/git\/torvalds\/linux.git\/commit\/?id=3f93aef535c8ea03e40cd8acf0753b3e6ed33e96\">has added<\/a><\/noindex> the ability to configure the compression level for the zstd algorithm, which can be considered an optimal compromise between the fast but inefficient lz4 and the slow yet highly compressing xz. Similarly to how a compression level could be set when applying zlib, support for the mount option '-o compress=zstd:level' has been added for zstd. In testing, the minimum first level provided data compression of 2.658 times with a compression speed of 438.47 MB\/s, decompression speed of 910.51 MB\/s, and memory consumption of 780 MB, whereas the maximum level 15 achieved a ratio of 3.126 times, but with a compression speed of 37.30 MB\/s, decompression speed of 878.84 MB\/s, and memory consumption of 2547 MB;\n<li class=\"l\"> <noindex><a rel=\"nofollow\" href=\"https:\/\/git.kernel.org\/pub\/scm\/linux\/kernel\/git\/torvalds\/linux.git\/plain\/Documentation\/device-mapper\/dm-init.txt?id=6bbc923dfcf57d6b97388819a7393835664c7a8e\">Added<\/a><\/noindex> the ability to boot from a filesystem located on a device-mapper without using initramfs. Starting from the current kernel release, the device-mapper can be used directly during the boot process, for example, as a partition with the root FS. The partition is configured using the boot parameter 'dm-mod.create'. Among the allowed device-mapper modules for booting are: 'crypt', 'delay', 'linear', 'snapshot-origin', and 'verity';\n<li class=\"l\"> In the Flash-oriented F2FS filesystem, a flag F2FS_NOCOW_FL has been added to disable copy-on-write mode for a given file;\n<li class=\"l\"> The filesystem <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=22084\">Exofs<\/a><\/noindex>, which is a variant of ext2 adapted for use with object storage devices (OSD), has been removed from the kernel.

Privileges are assigned through the definition in securityfs of rules based on a whitelist of permissible bindings (in the form 'UID1:UID2');\n<li class=\"l\"> Low-level changes have been added, necessary for the stacked organization of security module loading (LSM). A kernel boot parameter 'lsm' has been introduced, allowing control over which modules are loaded and in what order;\n<li class=\"l\"> Support for file namespace has been added to the audit subsystem.\n<li class=\"l\"> <noindex><a rel=\"nofollow\" href=\"https:\/\/git.kernel.org\/linus\/81a56f6dcd20\">Expanded<\/a><\/noindex> The GCC plugin structleak, which allows blocking potential memory content leaks, has been enhanced.

As part of the WiFi performance optimization project, the mac80211 stack now accounts for the distribution of air time and can allocate air time among multiple stations (in Access Point mode, less time for transmission is allocated to slow wireless stations, instead of evenly distributing time among all stations).\n<li class=\"l\"> A mechanism has been added \"<noindex><a rel=\"nofollow\" href=\"https:\/\/git.kernel.org\/pub\/scm\/linux\/kernel\/git\/torvalds\/linux.git\/commit\/?id=db2ab7a08f06\">devlink health<\/a><\/noindex>\", providing notifications when issues arise with the network interface;\n<\/ul>\n<li class=\"l\"> <b>Memory and system services<\/b>\n<ul>\n<li class=\"l\"> <noindex><a rel=\"nofollow\" href=\"https:\/\/git.kernel.org\/torvalds\/c\/a9dce6679d736cb3d612af39bab9f31f8db66f9b\">If the user refreshes the page in private browsing mode, Firefox will interpret this as a problem and suggest<\/a><\/noindex> Secure delivery of signals, considering the possibility of PID reuse.

To prevent such situations, a new system call pidfd_send_signal has been added, which uses file descriptors from \/proc\/pid to ensure stable binding to the process. Even if the PID gets reused during system call handling, the file descriptor will not change, allowing it to be safely used to send a signal to the process.\n<li class=\"l\"> <noindex><a rel=\"nofollow\" href=\"https:\/\/lwn.net\/Articles\/777212\/\">Added<\/a><\/noindex> the ability to use persistent memory devices (persistent-memory, for example <noindex><a rel=\"nofollow\" href=\"https:\/\/en.wikipedia.org\/wiki\/NVDIMM\">NVDIMM<\/a><\/noindex>) as RAM. Until now, similar devices were supported as storage devices, but they can now also be used as additional RAM. This capability was implemented in response to user requests willing to compromise on performance latency and wishing to use the native Linux kernel memory management API instead of existing user-space memory allocation systems that operate over mmap for the dax file;\n<li class=\"l\"> A new CPU idle handler has been added (cpuidle, determines when to put the CPU into deeper power-saving modes; the deeper the mode \u2014 the greater the savings, but more time is required to exit the mode) \u2014 TEO (Timer Events Oriented Governor). Previously, two cpuidle handlers were proposed \u2014 \"menu\" and \"ladder\", differing in their heuristics. The \"menu\" handler has known issues with making heuristic decisions; to eliminate these problems, a new handler was prepared. TEO is positioned as an alternative to the \"menu\" handler, allowing for higher performance while maintaining the same level of power consumption.<br \/>\nThe new handler can be activated using the boot parameter \"cpuidle.governor=teo\";<\/p>\n<li class=\"l\"> As part of the work to address <noindex><a rel=\"nofollow\" href=\"https:\/\/ru.wikipedia.org\/wiki\/%D0%9F%D1%80%D0%BE%D0%B1%D0%BB%D0%B5%D0%BC%D0%B0_2038_%D0%B3%D0%BE%D0%B4%D0%B0\">the year 2038 problem<\/a><\/noindex>, caused by overflow of the 32-bit time_t type, system calls have been included that offer 64-bit time counters for 32-bit architectures.

This capability enables the distribution of consolidated patches that cover several changes at once, instead of the complex process of sequentially applying live patches in a strictly defined order. Previously, each subsequent change had to be based on the state of the function after the previous change; now, it is possible to distribute several changes tied to a single initial state (i.e., maintain a single consolidated patch relative to the base kernel instead of a chain of interdependent patches);\n<li class=\"l\"> <noindex><a rel=\"nofollow\" href=\"https:\/\/git.kernel.org\/pub\/scm\/linux\/kernel\/git\/torvalds\/linux.git\/commit\/?id=eac616557050737a8d6ef6fe0322d0980ff0ffde\">Deprecated<\/a><\/noindex> is the support for a.out executable file format and<br \/>\n<noindex><a rel=\"nofollow\" href=\"https:\/\/git.kernel.org\/pub\/scm\/linux\/kernel\/git\/torvalds\/linux.git\/commit\/?id=08300f4402abc0eb3bc9c91b27a529836710d32d\">from the FreeBSD source tree.

It is noted that at the time of removal, all platforms that do not support Clang have switched to using external build tools installed from ports.
