From 63ded110979bdd8741542ec66fb9e2d2074aed8c Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Fri, 12 Jul 2024 15:52:27 +0200 Subject: [PATCH] uprobe: Change uretprobe syscall scope and number After discussing with Arnd [1] it's preferable to change uretprobe syscall number to 467 to omit the merge conflict with xattrat syscalls. Also changing the ABI to 'common' which will ease up the global scripts/syscall.tbl management. One consequence is we generate uretprobe syscall numbers for ABIs that do not support uretprobe syscall, but the syscall still returns -ENOSYS when called in that ABI.
