pstore: fix pstore filesystem mount/remount issue

2011-05-16T18:05:00+00:00

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.

pstore: fix one type of return value in pstore

2011-05-16T18:04:51+00:00

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: cleanups to pstore_dump()

2011-03-22T23:01:49+00:00

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.

pstore: use mount option instead sysfs to tweak kmsg_bytes

2011-03-21T20:50:05+00:00

/sys/fs is a somewhat strange way to tweak what could more
obviously be tuned with a mount option.

Some fixes for pstore

2011-03-18T02:08:13+00:00

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().

pstore: new filesystem interface to platform persistent storage

2010-12-28T22:25:21+00:00

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.
