From: Gustavo Zacarias Date: Tue, 27 Nov 2012 09:23:08 +0000 (+0000) Subject: ocf-linux: tweak kernel patch for newer kernels X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=670d60dc919fe6d99224ad1056c426812b38d108;p=buildroot.git ocf-linux: tweak kernel patch for newer kernels Newer kernels had a slight change in the random number API so the OCF patchset requires a slight tweak to build and run properly. Affected kernels are, per series: >=3.0.41, >=3.2.29, >=3.4.9, >=3.5.2 and any newer version. The fix is applied by detecting the API change rather than guessing the kernel version.
