Matthew Garrett	dee28e72b6	pstore: Allow the user to explicitly choose a backend ... pstore only allows one backend to be registered at present, but the system may provide several. Add a parameter to allow the user to choose which backend will be used rather than just relying on load order.

Luck, Tony	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.

Tony Luck	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. Signed-off-by: Tony Luck <tony.luck@intel.com>	2010-12-28 14:25:21 -08:00
