default n    4        help    5           This option enables
generic access to platform level    6           persistent
storage via "pstore" filesystem that can    7           be
mounted as /dev/pstore.  Only useful if you have    8
a platform level driver that registers with pstore to    9
provide the data, so you probably should just go say "Y"   10
(or "M") to a platform specific persistent store driver   11
(e.g. ACPI_APEI on X86) which will select this for you.   12
If you don't have a platform persistent store driver,   13
say N.   16        bool "Log kernel console messages"   17
depends on PSTORE   18        help   19          When the option
is enabled, pstore will log all kernel   20          messages,
even if no oops or panic happened.   22config PSTORE_FTRACE   23
