Brian Behlendorf	e554dffa60	SLES10 Fixes (part 9) ... - Proper ioctl() 32/64-bit binary compatibility. We need to ensure the ioctl data itself is always packed the same for 32/64-bit binaries. Additionally, the correct thing to do is encode this size in bytes as part of the command using _IOC_SIZE(). - Minor formatting changes to respect the 80 character limit. - Move all SPLAT_SUBSYSTEM_* defines in to splat-ctl.h. - Increase SPLAT_SUBSYSTEM_UNKNOWN because we were getting close to accidentally using it for a real registered subsystem.	2009-05-21 10:56:11 -07:00
Brian Behlendorf	7257ec4185	Fix taskq_wait() not waiting bug ... I'm very surprised this has not surfaced until now. But the taskq_wait() implementation work only wait successfully the first time it was called. Subsequent usage of taskq_wait() on the taskq would not wait. The issue was caused by tq->tq_lowest_id being set to MAX_INT after the first wait completed. This caused subsequent waits which check that the waiting id is less than the lowest taskq id to always succeed. The fix is to ensure that tq->tq_lowest_id is never set larger than tq->tq_next.id. Additional fixes which were added to this patch include: 1) Fix a race by placing the taskq_wait_check() in the tq->tq_lock spinlock. 2) taskq_wait() should wait for the largest outstanding id. 3) Multiple spelling corrections. 4) Added taskq wait regression test to validate correct behavior.	2009-03-15 15:13:49 -07:00
