Subject: [PATCH v2 0/6] 9p: Use IDRs more effectively
Date: Wed, 11 Jul 2018 14:02:19 -0700	[thread overview]
Message-ID: <20180711210225.19730-1-willy@infradead.org> (raw)

The 9p code doesn't take advantage of the IDR's ability to store
a pointer.  We can actually get rid of the p9_idpool abstraction
and the multi-dimensional array of requests.

v2: Address feedback from Dominique.

Matthew Wilcox (6):
  9p: Fix comment on smp_wmb
  9p: Change p9_fid_create calling convention
  9p: Replace the fidlist with an IDR
  9p: Embed wait_queue_head into p9_req_t
  9p: Use a slab for allocating requests
  9p: Remove p9_idpool
