Bug#339092: initramfs-tools: check if filesystem is already present in kernel
Package: initramfs-tools
Severity: minor
Tags: patch
This patch adds a separate function to load a filesystem driver which
first checks if it is already compiled into the kernel which should
remove some superflous modprobe error messages if it is.
