[PATCH 0/2] kernel: remove redundant static variable initializations

[Igor Putko]

This series removes explicit initializations of static bool variables to
false within the kernel/ subsystem. In C, static variables without explicit
initialization are implicitly placed in the .bss section and initialized
to zero/false by default. Removing these explicit initializations follows
the Linux kernel coding style and avoids cluttering the data section.

    stop_machine_initialized

[PATCH 1/2] kernel/workqueue: remove redundant initialization for static variables

[Igor Putko]

The static variables 'wq_topo_initialized' and 'wq_debug_force_rr_cpu'
are implicitly initialized to false. Remove the explicit initialization
to follow the Linux kernel coding style.

[PATCH 2/2] kernel/stop_machine: remove redundant initialization for stop_machine_initialized

[Igor Putko]

The static variable 'stop_machine_initialized' is implicitly initialized
to false. Remove the explicit initialization to follow the Linux
kernel coding style.

Please don't do whitespace patches. We can fix this whenever real
changes are required.
