commitfest. expand_table: Avoid a race condition which may have been contributing to the random corruption, panics and hangs we've been seeing in RAID-5 plexes, particularly with ata drives.

MFC: parityrebuild: write the parity block back to the correct

subdisk. HEADS UP: This fixes a serious data corruption bug when using the userland command 'rebuildparity'.

Tidy up splbio() protection.

transferred, do it in complete_rqe instead. launch_requests: Replace the inadvertently removed splbio() around the main loop. It may not be necessary, but the biggest test of this stuff are IDE disks, which I'm not using. Remove throttling code, I'm pretty sure it's not needed any more. Don't set B_ORDERED, it's not necessary either. Objected-to-by: alfred build_rq_buffer: Don't lose the B_ORDERED bit, it still has some residual meaning. To do this right, Vinum needs to look at the B_ORDERED bit and order the transfer across all disks involved. That's an exercise for another day. Objected-to-by: alfred Implicitly-sanctioned-by: jkh
