From: Matthew Wilcox Date: Thu, 11 Aug 2011 08:36:03 +0000 (+0200) Subject: Move some REQ flags to the common bio/request area X-Git-Tag: firefly_0821_release~3680^2~4613^2~4 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=8e4bf84474960e832b56293c9b0674c88b5b05ce;p=firefly-linux-kernel-4.4.55.git Move some REQ flags to the common bio/request area REQ_SECURE, REQ_FLUSH and REQ_FUA may all be set on a bio as well as on a request, so relocate them to the shared part of the enum.
