pstore: use mount option instead sysfs to tweak kmsg_bytes /sys/fs is a somewhat strange way to tweak what could more obviously be tuned with a mount option.

pstore: new filesystem interface to platform persistent storage Some platforms have a small amount of non-volatile storage that can be used to store information useful to diagnose the cause of a system crash. This is the generic part of a file system interface that presents information from the crash as a series of files in /dev/pstore. Once the information has been seen, the underlying storage is freed by deleting the files.
