I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 7061 files FOO.
I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah. I don't
know why I run into these diagnostics whereas others evidently do not.

We stopped adding "Contributed by" or similar lines in sources in 2012
in favour of git logs and keeping the Contributors section of the
glibc manual up to date. Removing these lines makes the license
header a bit more consistent across files and also removes the
possibility of error in attribution when license blocks or files are
copied across since the contributed-by lines don't actually reflect
reality in those cases.
Move all "Contributed by" and similar lines (Written by, Test by,
etc.) into a new file CONTRIBUTED-BY to retain record of these
contributions. These contributors are also mentioned in
manual/contrib.texi, so we just maintain this additional record as a
courtesy to the earlier developers.
The following scripts were used to filter a list of files to edit in
place and to clean up the CONTRIBUTED-BY file respectively. These
were not added to the glibc sources because they're not expected to be
of any use in future given that this is a one time task:

Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:

from the altered files, and then executing the following to cleanup:

Add:
int pthread_rwlock_clockrdlock (pthread_rwlock_t *rwlock,
clockid_t clockid,
const struct timespec *abstime)
and:
int pthread_rwlock_clockwrlock (pthread_rwlock_t *rwlock,
clockid_t clockid,
const struct timespec *abstime)
which behave like pthread_rwlock_timedrdlock and
pthread_rwlock_timedwrlock respectively, except they always measure
abstime against the supplied clockid. The functions currently support
CLOCK_REALTIME and CLOCK_MONOTONIC and return EINVAL if any other
clock is specified.

entry so that we fail even if it doesn't end up being used. Pass

(__pthread_rwlock_wrlock_full): Likewise.
* nptl/pthread_rwlock_rdlock.c: (__pthread_rwlock_rdlock): Pass
CLOCK_REALTIME to __pthread_rwlock_rdlock_full even though it won't
be used because there's no timeout.
* nptl/pthread_rwlock_wrlock.c (__pthread_rwlock_wrlock): Pass
CLOCK_REALTIME to __pthread_rwlock_wrlock_full even though it won't
be used because there is no timeout.
* nptl/pthread_rwlock_timedrdlock.c (pthread_rwlock_timedrdlock):
Pass CLOCK_REALTIME to __pthread_rwlock_rdlock_full since abstime
uses that clock.
* nptl/pthread_rwlock_timedwrlock.c (pthread_rwlock_timedwrlock):
Pass CLOCK_REALTIME to __pthread_rwlock_wrlock_full since abstime
uses that clock.

parameter to specify test clock. Use the magic clockid value of
CLOCK_USE_TIMEDLOCK to indicate that pthread_rwlock_timedrdlock and
pthread_rwlock_timedwrlock should be tested, otherwise pass the
specified clockid to pthread_rwlock_clockrdlock and

(do_test_clock): Renamed from do_test. Pass the necessary
thread_args when creating the reader and writer threads. Use
xpthread_create and xpthread_join.
(do_test): Call do_test_clock to test each clockid in turn.
* manual/threads.texi: Add documentation for
pthread_rwlock_clockrdlock and pthread_rwlock_clockwrclock.

Checked on x86_64-linux-gnu and i686-linux-gnu.
* nptl/tst-rwlock6.c: Use libsupport. This also happens to fix a
small bug where only tv.tv_usec was checked which could cause an
erroneous pass if pthread_rwlock_timedrdlock incorrectly took more
than a second.
* nptl/tst-rwlock7.c, nptl/tst-rwlock9.c, nptl/tst-rwlock14.c: Use
libsupport.

This replaces the pthread rwlock with a new implementation that uses a
more scalable algorithm (primarily through not using a critical section
anymore to make state changes). The fast path for rdlock acquisition and
