Subject: [PATCH 11/13] Fix "kmem -v" option on Linux 5.11-rc1 and later
|
|
kernels
|
|
|
|
Fix the "kmem -v" option on Linux 5.11-rc1 and later kernels
|
|
that contains commit 96e2db456135db0cf2476b6890f1e8b2fdcf21eb
|
|
("mm/vmalloc: rework the drain logic"). Without the patch,
|
|
the option will display nothing or fail with the error message
|
|
"kmem: invalid kernel virtual address: <address> type: "vmlist addr".
