[PATCH 1/2] Convert target drivers to use sbitmap
From: Matthew Wilcox <mawilcox at microsoft.com> The sbitmap and the percpu_ida perform essentially the same task, allocating tags for commands. Since the sbitmap is more used than the percpu_ida, convert the percpu_ida users to the sbitmap API.

[PATCH 0/3] Use sbitmap instead of percpu_ida
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

[PATCH 0/2] Use sbitmap instead of percpu_ida
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
