This patch moves suspend/resume to dev_pm_ops and add hibernation support.
It was tested on CSR SiRFprimaII cortex-a9 platform. A sd partition is used
as swsusp partition.

Nice catch. The patch itself looks okay, but I don't think the commit

Hi all,
Please excuse me, I have some noob question regarding MMC.
I'd like to erase(discard) certain MMC partition from kernel space (i.e. kernel
module).
I know this is quite ugly design, but I have no choice but to implement the
feature (erasing given MMC partition) within kernel space for

This also means we are able to skip writes that are not

My concern is more about what we actually can trust; either the GPIO irq
which likely is giving more than one irq when inserting/removing a card
since the slot is probably not glitch free, or that a rescan runs to make
sure a CMD13 is accepted from the previously inserted card.
Yes, I guess

Hi,
An overall question: How will you prevent each host driver from doing power
save operations while there is an ongoing BKOPS?
Power save operation could be to disable the clock to the card. Is that OK?
If not, I think we have two
