It doesn't appear to be documented in Documentation - case >insensitive grep for "stackdepot" gets no hits. No help text on its >Kconfig option. > >How are arch maintainers supposed to know anything about this? ok. Added reviewers/maintainers of stackdepot and KASAN(filter_irq_stack) code. Because on our ARM H/W it was causing memory issue, and without this change purpose of filter_irq_stack was gone as it was not filtering irq stacks. If anyone else has any views or comments for this.
