Re: [Xen-devel] [PATCH] SCHEDOP_block_masked

Introduce SCHEDOP_block_masked, which blocks a VCPU without enabling interrupts.We need this as there are circumstances where we cannot take interrupts,and are polling in a tight loop. In particular in Solaris's kernel debugger console input. We don't want to burn CPU in a domU, but we're not in a situation where we can safely use SCHEDOP_block.
Modified do_block() still checks event_pending, even if you do not clear the event_mask. Presumably you don't really want to do that?
