squashfs: bump 4.x, add lzo support We'll need libattr/xz packages in BR to enable support for those. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk> 2010-09-20 16:19:26 +02:00
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.
