From 903b1fc2737f1c7086420db0a1e550ba0b479a0c Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 17 Apr 2019 16:30:24 -0700 Subject: [PATCH] xfs: widen quota block counters to 64-bit integers Widen the incore quota transaction delta structure to treat block counters as 64-bit integers. This is a necessary addition so that we can widen the i_delayed_blks counter to be a 64-bit integer. Signed-off-by: Darrick J.
