Subject: [PATCH 0/3] Use sbitmap instead of percpu_ida
Date: Tue, 12 Jun 2018 12:05:42 -0700 [thread overview]
Message-ID: <20180612190545.10781-1-willy@infradead.org> (raw)
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
