+Cc: Érico Nogueira <ericonr@...root.org>
+Subject: [PATCH v3] add qsort_r and make qsort a wrapper around it
+
+we make qsort a wrapper by providing a wrapper_cmp function that uses
+the extra argument as a function pointer. should be optimized to a tail
+call on most architectures, as long as it's built with
+-fomit-frame-pointer, so the performance impact should be minimal.
+
+to keep the git history clean, for now qsort_r is implemented in qsort.c
+and qsort is implemented in qsort_nr.c.  qsort.c also received a few
+trivial cleanups, including replacing (*cmp)() calls with cmp().
+qsort_nr.c contains only wrapper_cmp and qsort as a qsort_r wrapper
+itself.
+---
+
+Following suggestions from IRC, as few changes as possible to the files,
+a final clean up commit after this one would involve some git mv's (I
+won't make a patch for it). Added weak_alias to force qsort to use
+libc's qsort_r.
+
+If this can't be accepted due to the overhead on some archs (ppc, mips,
+arm in some situations?), maybe we could revisit v2 of the patch?
