Subject: [PATCH 0/6] 9p: Use IDRs more effectively
Date: Thu, 28 Jun 2018 06:26:23 -0700 [thread overview]
Message-ID: <20180628132629.3148-1-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.
I haven't tested these patches, so caveat maintainer.
Matthew Wilcox (6):
9p: Change p9_fid_create calling convention
9p: Replace the fidlist with an IDR
9p: Embed wait_queue_head into p9_req_t
9p: Remove an unnecessary memory barrier
9p: Use a slab for allocating requests
9p: Remove p9_idpool
