+kmod 30
+=======
+
+- Improvements
+ - Stop adding duplicate information on modules.builtin.alias.bin, just use
+ the modules.builtin.bin index
+
+ - Speedup depmod, particularly under qemu with emulated arch, by
+ avoiding a lot of open/read/close of modules.alias.bin. On an
+ emulated ARM rootfs, depmod with only 2 modules was taking ~32s
+ vs ~0.07s now.
+
+ - Add kmod_module_new_from_name_lookup() which allows doing a lookup by
+ module name, without considering the aliases. Other than that search
+ order is similar to kmod_module_new_from_lookup().
+
+ - modinfo learned the --modname option to explicitely show information
+ about the module, even if there is an alias with the same name. This
+ allows showing information about e.g. kernel/lib/crc32.ko, even if
+ kernel also exports a crc32 alias in modules.alias:
+
+ alias crc32 crc32_pclmul
+ alias crc32 crc32_generic
+
+ Same behavior will be used to other modules and to aliases provided
+ by user/distro.
+
+ - depmod.conf learned a new "excludedir" directive so distro/user can
+ configure more directories to be excluded from its search, besides
+ the hardcoded values "build" and "source".
+
+ - Better group modprobe options on help output under "Management, Query and General".
+
+ - modprobe learned a --wait <MSEC> option to be used together with -r
+ when removing a module. This allows modprobe to keep trying the
+ removal if it fails because the module is still in use. An exponential backoff
+ time is used for further retries.
+
+ The wait behavior provided by the kernel when not passing O_NONBLOCK
+ to delete_module() was removed in v3.13 due to not be used and the
+ consequences of having to support it in the kernel. However there may
+ be some users, particularly on testsuites for individual susbsystems, that
+ would want that. So provide a userspace implementation inside modprobe for
+ such users. "rmmod" doesn't have a --wait as it remains a bare minimal over
+ the API provided by the kernel. In future the --wait behavior can be added
+ to libkmod for testsuites not exec'ing modprobe for module removal.
+
+ - kmod_module_remove_module() learned a new flag to silence output when
+ caller wants to handle them - this is particularly important for the
+ --wait flag to modprobe, as it's not desired to keep seeing error messages
+ while waiting for the module to be unused.
+
+ - Add SM3 hash algo support to modinfo output, as already available in the kernel.
+
+- Bug Fixes
+ - Fix modinfo output when showing information for a .ko module when running
+ on a kernel that has that module as builtin.
+
+ - Fix kmod_module_new_from_lookup() returning > 0 rather than 0
+ when it matches an alias.
+
+ - Fix modinfo segfault when module doesn't exist.
+
+ - Add missing function in the html documentation: kmod_get_dirname().
+
+ - Fix modprobe incorrectly handling number of arguments when prepending values from
+ MODPROBE_OPTIONS environment variable.
+
+ - Fix modprobe -r --remove-dependencies and since "dependencies" was a
+ misnomer, add the preferred argument option: "--remove-holders". This
+ is the same name used by the kernel. It allows users to also remove
+ other modules holding the one that is being removed.
+
+ - Fix off-by-one in max module name length in depmod.
+
+- Infra/internal
+ - Start some changes in the out-of-tree test modules in kmod so they are useful
+ for being really inserted in the kernel rather than relying on kmod's mock
+ interface. This helps manual testing and may be used to exercise to test
+ changes in the kernel.
