Subject: change __GFP_KSWAPD_RECLAIM from 0 to M_NOWAIT
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=d0c03c4f4dd4c9ec89d97b5b100a843da4433784;p=openbsd

change __GFP_KSWAPD_RECLAIM from 0 to M_NOWAIT

aja@ reported a panic where __i915_gpu_coredump() used a combination of
gfp flags which resulted in neither M_WAITOK or M_NOWAIT.
