3 pstore block oops/panic logger
9 pstore block (pstore/blk) is an oops/panic logger that writes its logs to a
11 these log files by mounting pstore filesystem like::

19 pstore/blk provides efficient configuration method for pstore/blk, which
23 Configurations for user determine how pstore/blk works, such as pmsg_size,
