From d002ebf1d8daa5a317645b1c4a3a0b7ea2abc9ac Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Mon, 10 Jan 2011 13:03:35 -0500 Subject: [PATCH] ext4: don't pass entire map to check_eofblocks_fl Since check_eofblocks_fl() only uses the m_lblk portion of the map structure, we may as well pass that directly, rather than passing the entire map, which IMHO obfuscates what parameters check_eofblocks_fl() cares about. Not a big deal, but seems tidier and less confusing, to me.
