From: Thomas Weißschuh Date: Sat, 18 Apr 2026 10:19:56 +0000 (+0200) Subject: tools/nolibc: also handle _llseek system call X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f38a0bb74576f418f264b8d407be8de7aac1f42a;p=thirdparty%2Fkernel%2Flinux.git tools/nolibc: also handle _llseek system call On some architectures the llseek system call contains a leading underscore. Treat it the same way as llseek and prefer it over the plain lseek system call as is necessary for 64-bit offset handling.
