Bug#271298: glibc: Please use nptl instead of linuxthreads on amd64
Package: glibc
Severity: wishlist
Tags: patch
The attached patch changes the following file of the glibc package:
* debian/sysdeps/amd64.mk:
Drop the 'nptl' pass from GLIBC_PASSES.
Use 'nptl' instead of 'linuxthreads' in the 'libc' pass (this requires
kernel >= 2.6.0, but 2.4 is not supported by the amd64 port anyway).
There had been some complaints about the default use of linuxthreads
(instead of nptl) on amd64.
In response to these complaints a glibc package with this patch applied
has been used by the amd64/gcc-3.4 experimental archive on alioth since
a few weeks (without problems so far).
Regards
Andreas Jochens
