From 73c8a80003d13be54e2309865030404441075182 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Mon, 5 Apr 2010 18:17:13 -0700 Subject: ocfs2: clean up localalloc mount option size parsing This patch pulls the local alloc sizing code into localalloc.c and provides a callout to it from ocfs2_fill_super(). Behavior is essentially unchanged except that I correctly calculate the maximum local alloc size. The old code in ocfs2_parse_options() calculated the max size as: ocfs2_local_alloc_size(sb) * 8 which is correct, in bits. Unfortunately though the option passed in is in megabytes. Ultimately, this bug made no real difference - the shrink code would catch a too-large size and bring it down to something reasonable. Still, it's less than efficient as-is.
