This patch removes conditionals on __ASSUME_O_CLOEXEC, and on O_CLOEXEC being defined, in sysdeps/unix/sysv/linux/, now that O_CLOEXEC support can be unconditionally assumed. The patch is conservative in what it changes and further followup cleanups may be possible. It may be possible to remove dl-opendir.c, but the patch does not do so, just removing a redundant undefine and redefine of __ASSUME_O_CLOEXEC. Also, __ASSUME_O_CLOEXEC is defined unconditionally for Hurd as well as Linux. Thus, if we decide that O_CLOEXEC support is a required feature of any glibc port, we could remove __ASSUME_O_CLOEXEC and all conditionals on it throughout glibc, rather than just cleaning up sysdeps/unix/sysv/linux/. Tested x86_64 that the disassembly of installed shared libraries is unchanged by this patch. * sysdeps/unix/sysv/linux/dl-opendir.c (__ASSUME_O_CLOEXEC): Do not undefine and redefine. * sysdeps/unix/sysv/linux/getsysstats.c (__get_nprocs) [O_CLOEXEC]: Make code unconditional. (__get_nprocs) [!O_CLOEXEC]: Remove conditional code. * sysdeps/unix/sysv/linux/shm_open.c: Do not include <kernel-features.h>. [O_CLOEXEC && !__ASSUME_O_CLOEXEC] (have_o_cloexec): Remove conditional variable definition. (shm_open) [O_CLOEXEC]: Make code unconditional. (shm_open) [!O_CLOEXEC || !__ASSUME_O_CLOEXEC]: Remove conditional code. |
