Quick update:
With this patch applied, at ~ 1.5 hours into the test, my system panic'd
[panic_on_oops set] with a BUG in __find_get_block() -- looks like the
BUG_ON() in check_irqs_on() called from bh_lru_install() inlined by
__find_get_block(). Before the panic occurred, I saw warnings from
native_smp_call_function_mask() [arch/x86/kernel/smp.c]--also because
irqs_disabled().
I'll back out the changes [spin_[un]lock() => spin_[un]lock_irq()] to
shrink_inactive_list() and try again. Just a hunch.
