[MTD] mtdoops: Perform write operations in a workqueue

2008-02-03T07:14:41+00:00

Writing to the flash needs to be done in a workqueue. The console
write functions may be called in any context which can lead to
lockups otherwise.

[MTD] Add sync/unblank function to mtdoops

2007-07-11T13:57:17+00:00

mtdoops wasn't ensuring data was flushed to flash in crash situations
after recent changes in mainline kernels as tracking the
oops_in_progress variable was no longer enough. We can use the "unblank"
console call as a sync call to tell us to write out the buffer though.

Therefore add a sync function to mtdoops and call this when console
unblank events occur.
