Subject: rbd: drop rbd_header_from_disk() gfp_flags parameter
X-Git-Tag: v3.6-rc1~36^2~29
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ed63f4fd9a88218ee709e8f57c36c0c5f219a7ad;p=platform%2Fkernel%2Flinux-exynos.git

rbd: drop rbd_header_from_disk() gfp_flags parameter

The function rbd_header_from_disk() is only called in one spot, and
it passes GFP_KERNEL as its value for the gfp_flags parameter.

Just drop that parameter and substitute GFP_KERNEL everywhere within
that function it had been used.  (If we find we need the parameter
again in the future it's easy enough to add back again.)
