Bug#601419: Linux support is available now
forwarded 601419 http://sources.redhat.com/bugzilla/show_bug.cgi?id=12193
thanks
Hi,
It seems that my Linux patch was finally accepted and is now queued
for Linux 2.6.40, see:
https://patchwork.linux-mips.org/patch/2302/
https://lkml.org/lkml/2011/5/12/112
Here's an updated version of the Glibc patch (also available in
http://sources.redhat.com/bugzilla/show_bug.cgi?id=12193)
