[Patch] fs/romfs/inode.c: trivial improvements

From: WANG Cong
Date: Wed Jul 18 2007 - 04:32:52 EST



1. There's no lists in fs/romfs/inode.c, so using list_entry is
a bit confusing. Replace it with container_of.

2. It is unnecessary to cast the return value of kmem_cache_alloc,
since it returns a void* pointer.

This patch is against 2.6.22.1.
