Subject: [PATCH 0/3] Use sbitmap instead of percpu_ida
Date:   Tue, 12 Jun 2018 12:05:42 -0700
Message-Id: <20180612190545.10781-1-willy@infradead.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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
 - Made iscsit_wait_for_tag static as pointed out by 0day

Matthew Wilcox (3):
  target: Abstract tag freeing
  Convert target drivers to use sbitmap
  Remove percpu_ida
