[linux-yocto] [PATCH v5.15-rt 08/11] bpf: Remove in_atomic() from bpf_link_put().

From: Sebastian Andrzej Siewior commit 87572f0f6aa8cbb3c69a7085fae70786cd217653 in linux-stable-rt bpf_free_inode() is invoked as a RCU callback. Usually RCU callbacks are invoked within softirq context. By setting rcutree.use_softirq=0 boot option the RCU callbacks will be invoked in a per-CPU

[linux-yocto] [PATCH v5.15-rt 01/11] io-mapping: don't disable preempt on RT in io_mapping_map_atomic_wc().

From: Sebastian Andrzej Siewior commit f1bd52382dcefb82cdc243575ab81f3966165b47 in linux-stable-rt io_mapping_map_atomic_wc() disables preemption and pagefaults for historical reasons. The conversion to io_mapping_map_local_wc(), which only disables migration, cannot be done wholesale because

From: Thomas Gleixner commit 71c09b1d6b07a7e4d8d1c686b53f8d1442f8ec14 in linux-stable-rt posix_timer_add() tries to allocate a posix timer ID by starting from the cached ID which was stored by the last successful allocation. This is done in a loop searching the ID space for a free slot one by

[linux-yocto] [PATCH v5.15-rt 02/11] locking/rwbase: Mitigate indefinite writer starvation

From: Sebastian Andrzej Siewior commit 47364f671cbed35071551bd911dc7b89a1761804 in linux-stable-rt On PREEMPT_RT, rw_semaphore and rwlock_t locks are unfair to writers. Readers can indefinitely acquire the lock unless the writer fully acquired the lock, which might never happen if there is

From: Thomas Gleixner commit ccf6bfd49a8a7d25bacc8e84ec5dbdfe513c29c3 in linux-stable-rt The recent fix to ensure atomicity of lookup and allocation inadvertently broke the pool refill mechanism. Prior to that change debug_objects_activate() and debug_objecs_assert_init() invoked

From: Peter Zijlstra commit 1992720dff250e9d7d99696588ab1b197160c6b6 in linux-stable-rt There is an explicit wait-type violation in debug_object_fill_pool() for PREEMPT_RT=n kernels which allows them to more easily fill the object pool and reduce the chance of allocation failures. Lockdep's

From: Wander Lairson Costa commit 20616d2c54d5db199f983ca9515630f361d5c995 in linux-stable-rt In put_task_struct(), a spin_lock is indirectly acquired under the kernel stock. When running the kernel in real-time (RT) configuration, the operation is dispatched to a preemptible context call to

From: Sebastian Andrzej Siewior commit f9fec545dea4aac71dfb54e3a6d187cc92af9ea4 in linux-stable-rt __build_all_zonelists() acquires zonelist_update_seq by first disabling interrupts via local_irq_save() and then acquiring the seqlock with write_seqlock(). This is troublesome and leads to
