RH-Commit: [3/5] f1329f5ce5f66033ead7777384dcc1613cad1226

Upstream Status: rhel-only
|
||
|
|
|
||
|
|
This hunk is part of upstream commit da3c22c74a3c
|
||
|
|
("linux-headers: Update to Linux v6.6-rc1"), but since that
|
||
|
|
commit updates a lot of files and does not apply cleanly,
|
||
|
|
we only focus on the necessary change here.
