From 2a3b1c6ea29db5d5dfe4602d0b0adfda88068de6 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Mon, 14 Jan 2013 17:30:23 -0500 Subject: [PATCH] mke2fs: the -g option will now specify the clusters per block group If bigalloc is enabled, then -g will specify the clusters per block group. (If bigalloc is not enabled, then a cluster == a block, so the meaning of -g is not changed.)
