You have sent him a patch that has triggered this response. He used to manually respond to these common problems, but in order to save his sanity (he kept writing the same thing over and over, yet to different people), I was created. Hopefully you will not take offence and will fix the problem in your patch and resubmit it so that it can be accepted into the Linux kernel tree. You are receiving this message because of the following common error(s) as indicated below: - This looks like a new version of a previously submitted patch, but you did not list below the --- line any changes from the previous version. Please read the section entitled "The canonical patch format" in the kernel file, Documentation/process/submitting-patches.rst for what needs to be done here to properly describe this. If you wish to discuss this problem further, or you have questions about how to resolve this issue, please feel free to respond to this email and Greg will reply once he has dug out from the pending patches received from other developers. thanks, greg k-h's patch email bot

I'm confused; I recall that the prior version kept the pr_warn(), but changed the test from a NULL check to instead use IS_ERR(). I'll state again that I think printing the error is useful, as it would provide an indication of why the debugfs directory isn't available. I also don't see an obvious way the error could be used to spam the dmesg. -J > > Signed-off-by: Wang Ming <machel@vivo.com> > --- > drivers/net/bonding/bond_debugfs.c | 3 --- > 1 file changed, 3 deletions(-) > > diff --git a/drivers/net/bonding/bond_debugfs.c > b/drivers/net/bonding/bond_debugfs.c > index 594094526..a41f76542 100644 > --- a/drivers/net/bonding/bond_debugfs.c > +++ b/drivers/net/bonding/bond_debugfs.c > @@ -87,9 +87,6 @@ void bond_debug_reregister(struct bonding *bond) > void bond_create_debugfs(void) > { > bonding_debug_root = debugfs_create_dir("bonding", NULL); > - > - if (!bonding_debug_root) > - pr_warn("Warning: Cannot create bonding directory in debugfs\n"); > } > > void bond_destroy_debugfs(void) > -- > 2.25.1 > >

It is expected that most callers should _ignore_ the errors return by debugfs_create_dir() in bond_debug_reregister(). Signed-off-by: Wang Ming <machel@vivo.com> --- drivers/net/bonding/bond_debugfs.c | 3 --- 1 file changed, 3 deletions(-)
