[PATCH v2 0/4] Fix ESRCH issues in pthread_cancel, pthread_kill

[Florian Weimer]

The new version fixes the support/Makefile update and puts the generic
“give me a non-reusable TID” functionality into a generic helper
function.

Tested on i686-linux-gnu and x86_64-linux-gnu.  Built with
build-many-glibcs.py.

Thanks,
Florian
