Do you have a git branch with these patches as well?

I had to keep the user space side on a private branch based on v4.2 since v4.3-rc1 didn't have a few fix from Adrian. V2 will be based on v4.3-rc4 and have all the patches (user and kernel space) on the same tree. > > Regards, > -- > Alex -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
