Subject: [PATCH v4 00/37] libpthread: Remove NPTL forwarders
Date: Fri, 16 Apr 2021 11:20:06 +0200 [thread overview]
Message-ID: <cover.1618564630.git.fweimer@redhat.com> (raw)
I was on pseudo-vacation for a while and then some urgent downstream
work came up. Sorry. I hope to return to libpthread work part-time
next week, and full time after that. Hopefully this will get us back on
track.
I believe this series addresses all of Adhemerval's review comments. It
switches to OTHER_SHLIB_COMPAT. I've retested this on i686-linux-gnu
and x86_64-linux-gnu, and built the entire thing with
build-many-glibcs.py.
Thanks,
Florian
