From e33b0351dae375105680dd70582a43ad89ac4bb8 Mon Sep 17 00:00:00 2001 From: xiao yang Date: Tue, 16 Jan 2018 15:26:55 +0800 Subject: [PATCH] common/xfs: Check if write supports [-c|-d] option in xfs_db Make sure _scratch_xfs_set_metadata_field() can be used on an old xfsprogs-dev(e.g. v3.1.1). The "-d" option was introduced since xfsprogs-dev v4.7.0 by commit 86769b3 ("xfs_db: allow recalculating CRCs on invalid metadata"). The special argument "--" is only used to end option-scanning in getopt(). getopt() was introduced since xfsprogs-dev v3.2.3 by commit c9f5e3d ("xfs_db: Allow writes of corrupted data")'.
