Subject: audit: Use kzalloc() instead of kmalloc()/memset() in audit_krule_to_data()
X-Git-Tag: ceph-for-6.19-rc5~283^2~1

audit: Use kzalloc() instead of kmalloc()/memset() in audit_krule_to_data()

Replace kmalloc+memset by kzalloc for better readability and simplicity.

This addresses the warning below:
WARNING: kzalloc should be used for data, instead of kmalloc/memset
