Subject: [PATCH 0/2] Make squashfs fragments' cache size more configurable

Hi All,

Currently, squashfs fragments' cache size is only determined by
config option CONFIG_SQUASHFS_FRAGMENT_CACHE_SIZE. Users have
no way to change the value when they get the binary kernel.
Now make it be configured when booting or inserting module.
Actually, it's better that a config option in a number format
in .config file cat be reconfigured during booting or inserting
module.

Thanks
Qixuan
