[PATCH 0/2] HRTICK reprogramming and optimization

Hi All, Hung tasks and RCU stall cases were reported on systems which were not 100% busy. Investigation of such unexpected cases (no sign of potential starvation caused by tasks hogging the system) pointed out that the periodic sched tick timer wasn't serviced anymore after a certain point and tha

[PATCH 2/2] sched/features: Distinguish between NORMAL and DEADLINE hrtick

The HRTICK feature has traditionally been servicing configurations that need precise preemptions point for NORMAL tasks. More recently, the feature has been extended to also service DEADLINE tasks with stringent runtime enforcement needs (e.g., runtime < 1ms with HZ=1000). Enabling HRTICK sched fe

[PATCH v2 1/2] mei: bus: simplify mei_cl_device_remove()

The driver core only calls a bus' remove function when there is actually a driver and a device. So drop the needless check and assign cldrv earlier. (Side note: The check for cldev being non-NULL is broken anyhow, because to_mei_cl_device() is a wrapper around container_of() for a member that is n

[PATCH v2 2/2] mei: bus: change remove callback to return void

The driver core ignores the return value of mei_cl_device_remove() so passing an error value doesn't solve any problem. As most mei drivers' remove callbacks return 0 unconditionally and returning a different value doesn't have any effect, change this prototype to return void and return 0 unconditi

[PATCH V2 3/4] Squashfs: add more sanity checks in inode lookup

Sysbot has reported an "slab-out-of-bounds read" error which has been identified as being caused by a corrupted "ino_num" value read from the inode. This could be because the metadata block is uncompressed, or because the "compression" bit has been corrupted (turning a compressed block into an unc

[PATCH V2 4/4] Squashfs: add more sanity checks in xattr id lookup

Sysbot has reported a warning where a kmalloc() attempt exceeds the maximum limit. This has been identified as corruption of the xattr_ids count when reading the xattr id lookup table. This patch adds a number of additional sanity checks to detect this corruption and others. 1. It checks for a c
