From 722278997bc964349e23e7061d541f8df3133a04 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Fri, 26 Aug 2016 15:59:50 +1000 Subject: xfs: fix some key handling problems in _btree_simple_query_range We only need the record's high key for the first record that we look at; for all records, we /definitely/ need the regular record key. Therefore, fix how the simple range query function gets its keys. Signed-off-by: Darrick J.
