Subject: mshv: use kmalloc_array in mshv_root_scheduler_init
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=c53763aa2b9c96fbabee68ebe1e13074cb09bfb2;p=thirdparty%2Flinux.git

mshv: use kmalloc_array in mshv_root_scheduler_init

Replace kmalloc() with kmalloc_array() to prevent potential
overflow, as recommended in Documentation/process/deprecated.rst.

No functional change.
