The patch titled
CONFIG_VM_EVENT_COUNTER comment decrustify
has been removed from the -mm tree. Its filename was
config_vm_event_counter-comment-decrustify.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: CONFIG_VM_EVENT_COUNTER comment decrustify
From: Paul Jackson <pj@xxxxxxx>
The VM event counters, enabled by CONFIG_VM_EVENT_COUNTERS, which provides
VM event counters in /proc/vmstat, has become more essential to
non-EMBEDDED kernel configurations than they were in the past. Comments in
the code and the Kconfig configuration explanation were stale, downplaying
their role excessively.
Refresh those comments to correctly reflect the current role of VM event
counters.
