Hi, all
We are planning to implement a kernel module called COLO Proxy to buffer and
compare packets. This module is one of the important component of COLO project
and now it is still in early stage, so any comments and feedback are warmly
welcomed, thanks in advance.

Hi Arnaldo
i encounter some problem when running perf test, the details arelike below:
-
[lizj@rhel71 perf]$ sudo ./perf test vfs_getname -v
61: Add vfs_getname probe to get syscall args filenames :
--- start ---
test child forked, pid 5958
Failed to find 'result'
handle a return of
DT_UNKNOWN.
-
so if we run the perf test under xfs, all cases under tests/shell/ will not be
covered previously.
