From bc8ca5b92d54f6f005fa73ad546f02fca26ddd85 Mon Sep 17 00:00:00 2001 From: Mimi Zohar Date: Sun, 24 Jan 2016 10:07:32 -0500 Subject: vfs: define kernel_read_file_id enumeration To differentiate between the kernel_read_file() callers, this patch defines a new enumeration named kernel_read_file_id and includes the caller identifier as an argument. Subsequent patches define READING_KEXEC_IMAGE, READING_KEXEC_INITRAMFS, READING_FIRMWARE, READING_MODULE, and READING_POLICY. Changelog v3: - Replace the IMA specific enumeration with a generic one.
