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.
