Same as 'perf probe -F', this patch adds filter support for the ftrace
subcommand option '-F, --funcs <[FILTER]>'.
Here is an example that only lists functions which start with 'vfs_':
$ sudo perf ftrace -F vfs_*
vfs_fadvise
vfs_fallocate
vfs_truncate
vfs_open
vfs_setpos
vfs_llseek
vfs_readf
vfs_w
Same as 'perf probe -F', this patch adds filter support for the ftrace
subcommand option '-F, --funcs <[FILTER]>'.
Here is an example that only lists functions which start with 'vfs_':
$ sudo perf ftrace -F vfs_*
vfs_fadvise
vfs_fallocate
vfs_truncate
vfs_open
vfs_setpos
vfs_llseek
vfs_readf
vfs_w
