kernel: io_uring/rw: defer fsnotify calls to task context

A locking context violation was found in the Linux kernel's iouring subsystem. The fsnotify calls were being made directly from kiocb completion context, which can execute in soft or hard IRQ context. This causes lockdep warnings when fsnotify attempts memory allocation with GFPKERNEL flags, whic...

kernel: rcu: Fix __this_cpu_read() lockdep warning in rcu_force_quiescent_state()

A lockdep warning was found in the Linux kernel's RCU subsystem. The rcuforcequiescentstate function incorrectly uses thiscpuread in preemptible code context. This macro requires preemption to be disabled, but the code can be called from preemptible context during rcutorture testing, triggering a...
