Message-Id: <1304461490-11056-19-git-send-email-tytso@mit.edu>
Date: Tue, 3 May 2011 18:24:48 -0400
From: Theodore Ts'o <tytso@....edu>
To: Ext4 Developers List <linux-ext4@...r.kernel.org>
Cc: Theodore Ts'o <tytso@....edu>
Subject: [PATCH 18/19] ext4: rename ext4_count_free_blocks() to ext4_count_free_clusters()
This function really counts the free clusters reported in the block
group descriptors, so rename it to reduce confusion.
Signed-off-by: "Theodore Ts'o" <tytso@....edu>
