I'm announcing the release of the 5.8.8 kernel. All users of the 5.8 kernel series must upgrade. The updated 5.8.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.8.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Documentation/devicetree/bindings/mmc/mtk-sd.txt | 2 Documentation/filesystems/affs.rst | 16 -

[PATCH] iio: trigger: Don't use RT priority

by Christian Eggers

Triggers may raise transactions on slow busses like I2C. Using the original RT priority of a threaded IRQ may prevent other important IRQ handlers from being run. In my particular case (on a RT kernel), the RT priority of the sysfstrig threaded IRQ handler caused (temporarily) raising the prio of a user space process which was holding the I2C bus mutex. Although this process did nothing more than blocking on i2c-dev ioctl(), no other threaded IRQ handlers (like DMA) were switched in during this time.

[PATCH 2/2] serial: core: fix console port-lock regression

by Johan Hovold

Fix the port-lock initialisation regression introduced by commit a3cb39d258ef ("serial: core: Allow detach and attach serial device for console") by making sure that the lock is again initialised during console setup. The console may be registered before the serial controller has been probed in which case the port lock needs to be initialised during console setup by a call to uart_set_options(). The console-detach changes introduced a regression in several drivers by effectively removing that initialisation by not initialising the lock when the port is used as a console (which is always the case during console setup). Add back the early lock initialisation and instead use a new console-reinit flag to handle the case where a console is being re-attached through sysfs. The question whether the console-detach interface should have been added in the first place is left for another discussion. Note that the console-enabled check in uart_set_options() is not redundant because of kgdboc, which can end up reinitialising an already enabled console (see commit 42b6a1baa3ec ("serial_core: Don't re-initialize a previously initialized spinlock.")).

[PATCH 1/2] serial: core: fix port-lock initialisation

by Johan Hovold

Commit f743061a85f5 ("serial: core: Initialise spin lock before use in uart_configure_port()") tried to work around a breakage introduced by commit a3cb39d258ef ("serial: core: Allow detach and attach serial device for console") by adding a second initialisation of the port lock when registering the port. As reported by the build robots [1], this doesn't really solve the regression introduced by the console-detach changes and also adds a second redundant initialisation of the lock for normal ports. Start cleaning up this mess by removing the redundant initialisation and making sure that the port lock is again initialised once-only for ports that aren't already in use as a console.
