From d349404ff14758dc9a2d3df032073ed795085860 Mon Sep 17 00:00:00 2001 From: David Chinner Date: Tue, 29 Apr 2008 12:53:15 +1000 Subject: [PATCH] [XFS] Don't double count reserved block changes on UP. On uniprocessor machines, the incore superblock is used for all in memory accounting of free blocks. in this situation, changes to the reserved block count are accounted twice; once directly and once via xfs_mod_incore_sb(). Seeing as the modification on SMP is done via xfs_mod_incore_sb(), make this the only update mechanism that UP uses as well.
