Subject: question about fs/jffs2/readinode.c
Date: Sat, 28 Apr 2012 07:06:16 +0200 (CEST)	[thread overview]
Message-ID: <alpine.DEB.2.02.1204280701210.1917@hadrien> (raw)

The function read_direntry in fs/jffs2/readinode.c contains the following 
code:

         err = jffs2_flash_read(c, (ref_offset(ref)) + read,
                                rd->nsize - already, &read, &fd->name[already]);
 	if (unlikely(read != rd->nsize - already) && likely(!err))
                       return -EIO;

         if (unlikely(err)) {
                 JFFS2_ERROR("read remainder of name: error %d\n", err);
                 jffs2_free_full_dirent(fd);
                 return -EIO;
         }

Is it intentional that the first if doesn't free fd?  At first I thought 
that that might be the case, because what would be the point of having two 
conditionals if they are going to do the same thing.  But I can't see why 
fd should not be freed either, so maybe the two conditionals are just 
there to give different error messages?

thanks,
julia
