Subject: [PATCH] apparmor: Use pointer to struct aa_label for lbs_cred
Git-commit: 37923d4321b1e38170086da2c117f78f2b0f49c6
Patch-mainline: v6.2-rc1
References: git-fixes
According to the implementations of cred_label() and set_cred_label(),
we should use pointer to struct aa_label for lbs_cred instead of struct
aa_task_ctx, this patch fixes it.
Fixes: bbd3662a8348 ("Infrastructure management of the cred security blob")
