[OS-BUILD PATCHv2] redhat/configs: Double MAX_LOCKDEP_ENTRIES

2021-07-22 Thread Waiman Long (via Email Bridge)
From: Waiman Long 

redhat/configs: Double MAX_LOCKDEP_ENTRIES

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1940075
Upstream: RHEL only

MAX_LOCKDEP_ENTRIES in lockdep is controlled by CONFIG_LOCKDEP_BITS. By
increasing it from a default of 15 to 16, we double MAX_LOCKDEP_ENTRIES
from 32k to 64k. That should be big enough for our internal use by our
QE.

CONFIG_LOCKDEP_BITS isn't used in generic kernel. It is only used
in debug kernel when CONFIG_LOCKDEP is turned on by the enabling of
CONFIG_PROVE_LOCKING.
