IRC: #glibc on OFTC.

Review new patches and restart review at the top.

 * 255 patches in NEW/NOBODY
 * Started at 53612.
 * GLIBC LoongArch PATCHES (caiyinyu)
  * LoongArch patch series for glibc.
  * Joseph Myers was previously reviewing this.
  * Several other developers reviewed parts of the series.
  * Review against existing v2
   * https://sourceware.org/pipermail/libc-alpha/2021-December/134811.html
  * LoongArch is not yet upstream in the kernel.
  * Need to have the port make its way into the kernel via linux-next.
  * With 5.19 slated for August, we need to consider if RC phase constants
    are good enough for a glibc port.
  * Could we merge and then backout of the port doesn't make 5.19?
 * 53573: [v3] elf: Rewrite long RESOLVE_MAP macro to a debug friendly function (guriev)
  * Fangrui was looking at earlier versions of the cleanup.
 * 53613: [v2] wcrtomb: Make behavior POSIX compliant (poyarekar)
  * Looking for review for v2 from earlier reviewers.
  * Adhemerval: Patch itself is OK, but need to check if the patch has consensus.
  * Carlos: Manual should say what you have *now* in the impl.
  * Siddhesh: Main concern is bumping symbol version because it avoids backports of
    the fix.
 * 53543: [v5] nptl: Add backoff mechanism to spinlock loop (Wangyang)
  * HJ reviewing. Should be committed today.
 * 53526: [v3] math: Add math-use-builtins-fabs (BZ#29027)
  * Joseph pointed out issues.
  * Followed up with suggestions. Just a code cleanup.
  * Should not change code generation.
 * 53523: [PATCH v4 1/3] ia64: Always define IA64_USE_NEW_STUB as a flag macro
  * Adhemerval and Florian discussing consensus.
  * Adhemerval: Move mmap call to internal definition. So we can use the same logic.
  * https://sourceware.org/pipermail/libc-alpha/2022-May/138524.html
  * Florian to review.
 * 53519: Args adjustment with ./ld.so exe [BZ #23293] (v6)
  * Need 1 and 4 patches reviewed.
  * Florian: The first patch needs reivew.
 * Stopped at 53519.
 * Florian: vfprintf not that high priority.
  * Someone should look at the buffer abstraction.
  * Series 7969.
  * Patch 17 implements the abstraction.
 * Arjun: pthread_atfork v2.
 * Adhemerval:
  * Fallback clone on posix_spawn failure.
   * Ask Christian Brauner about the vDSO issue.
   * There is conflict here with the semantics.
