• 06cf91b4b   pstore: fix pstore filesystem mount/remount issue ... Browse Code »

  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.

• 8d38d74b6   pstore: fix one type of return value in pstore ... Browse Code »

  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.

• 9f6af27fb   pstore: cleanups to pstore_dump() ... Browse Code »

  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.

• 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.
