| Subject: [PATCH] lapi/pidfd: adding pidfd header file |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |
| Content-Transfer-Encoding: 8bit |
| |
| The newer Glibc already provided wrapper for the series pidfd syscall, |
| so let's include the header file conditionally. |
| |
| # rpm -q glibc-devel |
| glibc-devel-2.35.9000-31.fc37.ppc64le |
| # rpm -ql glibc-devel | grep pidfd |
| /usr/include/sys/pidfd.h |
| |
| To get rid of compiling error from fedora-rawhide: |
| |
| tst_safe_macros.c: In function ‘safe_pidfd_open’: |
| tst_safe_macros.c:135:16: error: implicit declaration of function ‘pidfd_open’ [-Werror=implicit-function-declaration] |
| 135 | rval = pidfd_open(pid, flags); |
| | ^~~~~~~~~~ |
