[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

[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
