[Ocfs2-devel] [PATCH 2/6] ocfs2: Require an inode for ocfs2_read_block(s)().

Joel Becker joel.becker at oracle.com
Thu Oct 9 17:20:30 PDT 2008


Now that synchronous readers are using ocfs2_read_blocks_sync(), all
callers of ocfs2_read_blocks() are passing an inode.  Use it
unconditionally.  Since it's there, we don't need to pass the
ocfs2_super either.
