The patch titled
Subject: idr: rename MAX_LEVEL to MAX_IDR_LEVEL
has been removed from the -mm tree. Its filename was
idr-rename-max_level-to-max_idr_level.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Fengguang Wu <fengguang.wu@xxxxxxxxx>
Subject: idr: rename MAX_LEVEL to MAX_IDR_LEVEL
To avoid name conflicts:
drivers/video/riva/fbdev.c:281:9: sparse: preprocessor token MAX_LEVEL redefined
While at it, also make the other names more consistent and add
parentheses.
