• 56280682c   pstore: Add extra context for writes and erases ... Browse Code »

  EFI only provides small amounts of individual storage, and conventionally
  puts metadata in the storage variable name. Rather than add a metadata
  header to the (already limited) variable storage, it's easier for us to
  modify pstore to pass all the information we need to construct a unique
  variable name to the appropriate functions.

• 638c1fd30   pstore: Extend API for more flexibility in new backends ... Browse Code »

  Some pstore implementations may not have a static context, so extend the
  API to pass the pstore_info struct to all calls and allow for a context
  pointer.

• 366f7e7a7   pstore: use mount option instead sysfs to tweak kmsg_bytes ... Browse Code »

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

• fbe0aa1f3   Some fixes for pstore ... Browse Code »

  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().

• ca01d6dd2   pstore: new filesystem interface to platform persistent storage ... Browse Code »

  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.
