From 19b303d8b5a0e8150a4697c01ca03e75a0a17469 Mon Sep 17 00:00:00 2001 From: Zheng Liu Date: Thu, 8 Nov 2012 14:34:04 -0500 Subject: [PATCH] ext4: print map->m_flags in trace_ext4_ext/ind_map_blocks_exit When we use trace_ext4_ext/ind_map_blocks_exit, print the value of map->m_flags in order that we can understand the extent's current status.
