Subject: - ext3-balloc-say-rb_entry-not-list_entry.patch removed from -mm tree


The patch titled
     ext3 balloc: say rb_entry not list_entry
has been removed from the -mm tree.  Its filename was
     ext3-balloc-say-rb_entry-not-list_entry.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: ext3 balloc: say rb_entry not list_entry
From: Hugh Dickins <hugh@...itas.com>

The reservations tree is an rb_tree not a list, so it's less confusing to use
rb_entry() than list_entry() - though they're both just container_of().
