It is not working here:
[root@jouet mnt]# perf test -v 62 62: Check open filename arg using perf trace + vfs_getname: --- start --- test child forked, pid 4919 Added new event: probe:vfs_getname (on getname_flags:72 with pathname=result->name:string)
You can now use it in all perf tools, such as:
perf record -e probe:vfs_getname -aR sleep 1
test child finished with -1 ---- end ---- Check open filename arg using perf trace + vfs_getname: FAILED! [root@jouet mnt]#
and when I run this with strace -e open to see if it is picking the right script, it is:
open("/home/acme/libexec/perf-core/tests/shell/record+script_probe_vfs_getname.sh", O_RDONLY) = 4 open("/home/acme/libexec/perf-core/tests/shell/trace+probe_libc_inet_pton.sh", O_RDONLY) = 4 open("/home/acme/libexec/perf-core/tests/shell/trace+probe_vfs_getname.sh", O_RDONLY) = 4 62: Check open filename arg using perf trace + vfs_getname: --- start --- test child forked, pid 4947 Added new event: probe:vfs_getname (on getname_flags:72 with pathname=result->name:string)
You can now use it in all perf tools, such as:
perf record -e probe:vfs_getname -aR sleep 1

So can you please check if the file you're using is the one in this patch submission?
