This patch is severely whitespace damaged. Can you fix your MUA
or try to use git-send-email?

The changelog as well is of low quality. Maybe something like this:

infiniband: cxgb4: fix memory skb memory leak

... would be better.

Also, this fails the build, due to the extra dot character after
the comment. :-(



Agreed.  Start over with this patch,  do what we asked, and make sure it 
passes checkpatch...




Thanks,
Levente Kurusa.

AFAIK, checkpatch.pl will show you a message if it detects this:

if (x)
kfree(x);

so I guess it is not really needed.

 Can you change the comment?  This patch is now fixing a potential skb leak.
 Also, kfree_sb() will ignore NULL ptrs, so we could just always call it.
 But I'd add a comment like /* NULL is ignored */.

 Thanks,

 Steve.

This patch is severely whitespace damaged. Can you fix your MUA
or try to use git-send-email?

The changelog as well is of low quality. Maybe something like this:

infiniband: cxgb4: fix memory skb memory leak

... would be better.

Also, this fails the build, due to the extra dot character after
the comment. :-(

Thanks,
Levente Kurusa.

Agreed.  Start over with this patch,  do what we asked, and make sure it 
passes checkpatch...

Can we close this bug or is it still a issue as we can'
return NULL from kfree or kfree_skb. Here is the bug
ID 44631 I would close it if we are done with the bug
otherwise I think there are no other issues with
allocating a skb,



In what database is this bug ID 44631?
