Subject: Re: [PATCH] avoid NULL deference in ext2_xattr_get
Date: Sat, 10 Jul 2010 11:21:52 +0200	[thread overview]

Another way to fix this would be to say:

   	ea_idebug(inode, "name=%d.%s, buffer=%p, buffer_size=%ld",
-  		  name_index, name, buffer, (long)buffer_size);
+  		  name_index, name ?: "(null)", buffer, (long)buffer_size);

That would help for debugging.

regards,
dan carpenter
