Message-Id: <1343684862-13181-5-git-send-email-tytso@mit.edu> Date: Mon, 30 Jul 2012 17:47:40 -0400 From: Theodore Ts'o <tytso@....edu> To: Ext4 Developers List <linux-ext4@...r.kernel.org> Cc: tony@...eyournoodle.com, Theodore Ts'o <tytso@....edu> Subject: [PATCH 5/7] libext2fs: call numeric_progress functions through a operations struct Instead of calling ext2fs_numeric_progress_*() directly from closefs.c and alloc_tables.c, call it via a operations structure which is only initialized by the one program (mke2fs) which needs it. This reduces the number of C library symbols needed by boot loader systems such as yaboot.
