Subject: [PATCH] mm: disable CONFIG_PER_VMA_LOCK by default until its fixed
|
|
||||||
|
|
||||||
A memory corruption was reported in [1] with bisection pointing to the
|
|
||||||
patch [2] enabling per-VMA locks for x86.
|
|
||||||
Disable per-VMA locks config to prevent this issue while the problem is
|
|
||||||
being investigated. This is expected to be a temporary measure.
