366f7e7a79 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.

ca01d6dd2d 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.
