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.

* nptl: Move pthread_setattr_default_np into libcFlorian Weimer2021-05-111-2/+8
| | | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. The export of __default_pthread_attr_freeres is temporary. There is a minor regression in freeres coverage because in the dynamic case, __default_pthread_attr_freeres is no longer called if libpthread is not linked in.

* nptl: Destroy the default thread attribute as part of freeresFlorian Weimer2020-06-021-0/+10

* nptl: Change type of __default_pthread_attrFlorian Weimer2020-06-021-3/+3
| | | | | | | | | | | | union pthread_attr_transparent has always the correct size, even if pthread_attr_t has padding that is not present in struct pthread_attr. This should not result in an observable behavioral change. The existing code appears to have been correct, but it was brittle because it was not clear which functions were allowed to write to an entire pthread_attr_t argument (e.g., by copying it).

* nptl: Change tst-typesizes to _Static_assertAdhemerval Zanella2017-11-071-2/+0

* Remove CPU set size checking from affinity functions [BZ #19143]Florian Weimer2015-11-241-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With current kernel versions, the check does not reliably detect that unavailable CPUs are requested, for these reasons: (1) The kernel will silently ignore non-allowed CPUs, that is, CPUs which are physically present but disallowed for the thread based on system configuration. (2) Similarly, CPU bits which lack an online CPU (possible CPUs) are ignored. (3) The existing probing code assumes that the CPU mask size is a power of two and at least 1024. Neither has it to be a power of two, nor is the minimum possible value 1024, so the value determined is often too large. This means that the CPU set size check in glibc accepts CPU bits beyond the actual hard system limit. (4) Future kernel versions may not even have a fixed CPU set size. After the removal of the probing code, the kernel still returns EINVAL if no CPU in the requested set remains which can run the thread after the affinity change. Applications which care about the exact affinity mask will have to query it using sched_getaffinity after setting it. Due to the effects described above, this commit does not change this. The new tests supersede tst-getcpu, which is removed. This addresses bug 19164 because the new tests allocate CPU sets dynamically. * nptl/check-cpuset.h: Remove. * nptl/pthread_attr_setaffinity.c (__pthread_attr_setaffinity_new): Remove CPU set size check. * nptl/pthread_setattr_default_np.c (pthread_setattr_default_np): Likewise. * sysdeps/unix/sysv/linux/check-cpuset.h: Remove. * sysdeps/unix/sysv/linux/pthread_setaffinity.c (__kernel_cpumask_size, __determine_cpumask_size): Remove.

* New API to set default thread attributesSiddhesh Poyarekar2013-06-151-0/+110
This patch introduces two new convenience functions to set the default thread attributes used for creating threads. This allows a programmer to set the default thread attributes just once in a process and then run pthread_create without additional attributes.
