From 86e59436d406d833a5da4a94aefb3c3be6b26053 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Tue, 22 Nov 2016 13:40:27 -0800 Subject: [PATCH] ocfs2: charge quota for reflinked blocks When ocfs2 shares blocks from one file to another, it's necessary to charge that many blocks to the quota because ocfs2 tallies block charges according to the number of blocks mapped, not the number of physical blocks used. Without this patch, reflinking X blocks and then CoWing all of them causes quota usage to *decrease* by X as seen in generic/305. Signed-off-by: Darrick J.
