fs/squashfs: honour the number of parallel jobs By default, mksquashfs uses all the CPUs available, like us with BR2_JLEVEL=0. However, by setting BR21_JLEVEL to non-zero, a user volutarily limits the number of jobbs allowed to run concurrently (for various reasons, like this is not a priority task on the machine; or like the autobuilders, to spread the load accross multiple runs without overloading the machine). So, propagate tthe parallelisn settings down to mksquashfs, to repect the user's will. Signed-off-by: "Yann E.

fs: make it behave a bit more like the package infra Currently, to register a filesystem, one has to call: $(eval $(call ROOTFS_TARGET,blabla)) This is very unlike the package infrastructure, where the name of the package is automatically guessed by the infra. It turns out that we can now do that for the filesystem infra too. Signed-off-by: "Yann E.
