[PATCH 0/6] 9p: Use IDRs more effectively

From: Matthew Wilcox
Date: Thu Jun 28 2018 - 09:27:05 EST


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
