From 6aa7a29aa8378fa868fabef6a84b0a40d5d9d677 Mon Sep 17 00:00:00 2001 From: Daniel M. Weeks Date: Mon, 7 Apr 2014 15:39:16 -0700 Subject: initramfs: debug detected compression method This can greatly aid in narrowing down the real source of initramfs problems such as failures related to the compression of the in-kernel initramfs when an external initramfs is in use as well. Existing errors are ambiguous as to which initramfs is a problem and why. [akpm@linux-foundation.org: use pr_debug()] Signed-off-by: Daniel M.
