From: Matthew Wilcox <mawilcox at microsoft.com> This is a pretty rough-and-ready conversion of the target drivers from using percpu_ida to sbitmap. It compiles; I don't have a target setup, so it's completely untested. I haven't tried to do anything particularly clever here, so it's possible that, for example, the wait queue in iscsi_target_util could be more clever, like

Removing the percpu_ida code nets over 400 lines of removal. It's not as spectacular as deleting an entire architecture, but it's still a worthy reduction in lines of code. Untested due to lack of hardware and not understanding how to set up a target platform. Changes from v1: - Fixed bugs pointed out by Jens in iscsit_wait_for_tag() - Abstracted out tag freeing as requested by Bart

This patch makes vhost_scsi_flush() wait for all the pending requests issued before the flush operation to be finished. Changes in v4: - Introduce vhost_scsi_inflight - Drop array to track flush Changes in v3: - Rebase - Drop 'tcm_vhost: Wait for pending requests in vhost_scsi_clear_endpoint()' in this series, we already did that in 'tcm_vhost: Use vq->private_data to indicate
