X-Git-Tag: upstream/snapshot3+hdmi~30758^2~848
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0ec0b7ac3cdfb8635d75aead5733f7a424ea4ad3;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

[MAC80211]: use more GFP_KERNEL instead of GFP_ATOMIC

This patch replaces atomic allocations with regular ones where possible.

Merged with "revert some GFP_ATOMIC -> GFP_KERNEL changes" from Michael Wu:
> Some of the allocations made with GFP_ATOMIC really were necessary.
