Subject: [PATCH v2 00/26] pstore, mmc: add mmc as backend for pstore
Newsgroups: gmane.linux.kernel
Date: Thursday 8th November 2012 13:05:58 UTC (over 3 years ago)
From: Dragos Tatulea 

These patches enable using the mmc card to store panic information.

They include changes for pstore and mmc:
 - add block device backend for pstore
 - add logic in mmc for writing in panic mode

A mmc host driver must implement mmc_panic_ops. This patchset contains
an implementation for sdhci.

v2:
    - Added some detailed description to some commits. Not all of them
though because they are very small and self explanatory.
    - Added clarification on what mmc host controller drivers have to
implement to support panic dumping.

  pstore: allow for big files
  pstore: add flags
  pstore: add flush
