From: Martin Kaiser Date: Tue, 28 Apr 2026 14:38:47 +0000 (+0200) Subject: perf test: Fix sys_enter_openat event test for musl X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9a4a67dddc3d88e2e9d3cff462b943f40ea439e4;p=thirdparty%2Flinux.git perf test: Fix sys_enter_openat event test for musl The "syscalls:sys_enter_openat event fields" test calls openat(AT_FDCWD, "/etc/passwd", O_RDONLY | O_DIRECTORY) and verifies that the flags of the captured event are matching. This fails for musl, where the openat syscall wrapper always adds O_LARGEFILE. Update the check to allow for additional flags, the access mode flags must be unchanged.
