From: Daniel Vetter Date: Fri, 12 Jun 2020 07:05:35 +0000 (+0200) Subject: dma-buf: minor doc touch-ups X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=102514ec73ed54b2681ff225e78e965e4fbe43ef;p=uclinux-h8%2Flinux.git dma-buf: minor doc touch-ups Just some tiny edits: - fix link to struct dma_fence - give slightly more meaningful title - the polling here is about implicit fences, explicit fences (in sync_file or drm_syncobj) also have their own polling v2: I misplaced the .rst include change corresponding to this patch.
