Subject: perf trace: Set errpid to false for rseq and set_robust_list
X-Git-Tag: v6.16-rc1~57^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8c56bfe53bd881c7b598c54a3a06216743c57bbc;p=thirdparty%2Flinux.git

perf trace: Set errpid to false for rseq and set_robust_list

The 'rseq' and 'set_robust_list' syscalls don't return a pid, so set
errpid for both to false.

Fixes: 0c1019e3463b263a ("perf trace: Mark the 'rseq' arg in the rseq syscall as coming from user space")
Fixes: 1de5b5dcb8353f36 ("perf trace: Mark the 'head' arg in the set_robust_list syscall as coming from user space")

[ Remove explicit .errpid = false, omitting its initialization zeroes it, as noted by Namhyung ]
