Currently after mount/remount operation on pstore filesystem, the content on pstore will be lost. It is because current ERST implementation doesn't support multi-user usage, which moves internal pointer to the end after accessing it. Adding multi-user support for pstore usage.

the return type of function _read_ in pstore is size_t, but in the callback function of _read_, the logic doesn't consider it too much, which means if negative value (assuming error here) is returned, it will be converted to positive because of type casting. ssize_t is enough for this function.

pstore_dump() can be called with many different "reason" codes. Save the name of the code in the persistent store record. Also - only worthwhile calling pstore_mkfile for KMSG_DUMP_OOPS - that is the only one where the kernel will continue running.

/sys/fs is a somewhat strange way to tweak what could more obviously be tuned with a mount option. Suggested-by: NChristoph Hellwig <hch@infradead.org> Signed-off-by: NTony Luck <tony.luck@intel.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

1) Change from ->get_sb() to ->mount() 2) Use mount_single() instead of mount_nodev() 3) Pulled in ramfs_get_inode() & trimmed to what I need for pstore 4) Drop the ugly pstore_writefile() Just save data using kmalloc() and provide a pstore_file_read() that uses simple_read_from_buffer().

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: NTony Luck <tony.luck@intel.com>
