Subject: [PATCH 51/87] lockdep, bug: Exclude TAINT_FIRMWARE_WORKAROUND from
|
|
disabling lockdep
|
|
|
|
commit df754e6af2f237a6c020c0daff55a1a609338e31 upstream.
|
|
|
|
It's unlikely that TAINT_FIRMWARE_WORKAROUND causes false
|
|
lockdep messages, so do not disable lockdep in that case.
|
|
We still want to keep lockdep disabled in the
|
|
TAINT_OOT_MODULE case:
|
|
|
|
- bin-only modules can cause various instabilities in
|
|
their and in unrelated kernel code
|
|
|
|
- they are impossible to debug for kernel developers
|
|
|
|
- they also typically do not have the copyright license
|
|
permission to link to the GPL-ed lockdep code.
