2023-02-14dm: send just one event on resize, not twoMikulas Patocka
Device mapper sends an uevent when the device is suspended, using the function set_capacity_and_notify. However, this causes a race condition with udev. Udev skips scanning dm devices that are suspended. If we send an uevent while we are suspended, udev will be racing with device mapper resume code. If the device mapper resume code wins the race, udev will process the uevent after the device is resumed and it will properly scan the device. However, if udev wins the race, it will receive the uevent, find out that the dm device is suspended and skip scanning the device. This causes bugs such as systemd unmounting the device - see https://bugzilla.redhat.com/show_bug.cgi?id=2158628 This commit fixes this race. We replace the function set_capacity_and_notify with set_capacity, so that the uevent is not sent at this point. In do_resume, we detect if the capacity has changed and we pass a boolean variable need_resize_uevent to dm_kobject_uevent. dm_kobject_uevent adds "RESIZE=1" to the uevent if need_resize_uevent is set.

2023-02-14spi: STIG Mode Fixes for spi-cadence-qspi driverMark Brown
Merge series from Dhruva Gole <d-gole@ti.com>: * Reset the CMD_CTRL Register, without which read/writes in STIG mode were failing in some cases. The issue came to light while using STIG Mode for small reads. * Also add a flag that can allow us to do direct reads but distinguish direct writes, thus enabling us to disable writes in DAC mode in some cases that require it. (Like to write to some connected Flash registers) * Fix register reads in STIG mode and also use STIG mode while reading flash registers. Currently if you try to read a register while in STIG mode there is no support for ADDR and thus naturally a register never gets read from the flash. This patch series has been tested on a TI AM625-SK-EVM with both a quad spi nor flash (s25hs) and OSPI NOR Flash (s28hs). Output of ltp-ddt test, "DD_RW_ERASESIZE_UBIFS" run with s25hs512t flash: ...

2023-02-15setlocalversion: use only the correct release tag for git-describeMasahiro Yamada
Currently, setlocalversion uses any annotated tag for git-describe. If we are at a tagged commit, it will not append the commit hash. $ git checkout v6.2-rc1^ $ make -s defconfig kernelrelease 6.1.0-14595-g292a089d78d3 $ git tag -a foo -m foo $ make -s kernelrelease 6.1.0 If a local tag 'foo' exists, it pretends to be a released version '6.1.0', while there are many commits on top of it. The output should be consistent irrespective of such a local tag. Pass the correct release tag to --match option of git-describe. In the mainline kernel, the SUBLEVEL is always '0', which is omitted from the tag. KERNELVERSION annotated tag 6.1.0 -> v6.1 (mainline) 6.2.0-rc5 -> v6.2-rc5 (mainline, release candidate) 6.1.7 -> v6.1.7 (stable) To preserve the behavior in linux-next, use the tag derived from localversion* files if exists. In linux-next, the local version is specified by the localversion-next file. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
