pstore: Allow the user to explicitly choose a backend

2011-07-22T23:14:39+00:00

pstore only allows one backend to be registered at present, but the
system may provide several. Add a parameter to allow the user to choose
which backend will be used rather than just relying on load order.

pstore: Make "part" unsigned

2011-07-22T23:14:29+00:00

We'll never have a negative part, so just make this an unsigned int.

pstore: Add extra context for writes and erases

2011-07-22T23:14:20+00:00

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.

pstore: Extend API for more flexibility in new backends

2011-07-22T23:14:06+00:00

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.

pstore: fix pstore filesystem mount/remount issue

2011-05-16T18:05:00+00:00

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.

pstore: fix one type of return value in pstore

2011-05-16T18:04:51+00:00

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.

pstore: cleanups to pstore_dump()

2011-03-22T23:01:49+00:00

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.

pstore: use mount option instead sysfs to tweak kmsg_bytes

2011-03-21T20:50:05+00:00

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