mmc: fix all hangs related to mmc/sd card insert/removal during suspend/resume 2011-11-02T03:13:53+00:00 Maxim Levitsky maximlevitsky@gmail.com 2010-08-11T01:01:41+00:00 24d5b5e1f5c6c730f24461e35d392e40488e8bf0 commit 4c2ef25fe0b847d2ae818f74758ddb0be1c27d8e upstream. If you don't use CONFIG_MMC_UNSAFE_RESUME, as soon as you attempt to suspend, the card will be removed, therefore this patch doesn't change the behavior of this option. However the removal will be done by pm notifier, which runs while userspace is still not frozen and thus can freely use del_gendisk, without the risk of deadlock which would happen otherwise. Card detect workqueue is now disabled while userspace is frozen, Therefore if you do use CONFIG_MMC_UNSAFE_RESUME, and remove the card during suspend, the removal will be detected as soon as userspace is unfrozen, again at the moment it is safe to call del_gendisk. Tested with and without CONFIG_MMC_UNSAFE_RESUME with suspend and hibernate.

commit 4c2ef25fe0b847d2ae818f74758ddb0be1c27d8e upstream.

If you don't use CONFIG_MMC_UNSAFE_RESUME, as soon as you attempt to
suspend, the card will be removed, therefore this patch doesn't change the
behavior of this option.

However the removal will be done by pm notifier, which runs while
userspace is still not frozen and thus can freely use del_gendisk, without
the risk of deadlock which would happen otherwise.

Card detect workqueue is now disabled while userspace is frozen, Therefore
if you do use CONFIG_MMC_UNSAFE_RESUME, and remove the card during
suspend, the removal will be detected as soon as userspace is unfrozen,
again at the moment it is safe to call del_gendisk.

Tested with and without CONFIG_MMC_UNSAFE_RESUME with suspend and hibernate.

net: Reorder incoming packets in PPPoLAC and PPPoPNS. 2011-09-05T02:01:19+00:00 Chia-chi Yeh chiachi@android.com 2011-04-15T22:22:09+00:00 c1e09e5cce158d76e0a641c5bd829c142ee686c8 PPP handles packet loss but does not work with out of order packets. This change performs reordering of incoming data packets within a sliding window of one second. Since sequence number is optional, receiving a packet without it will drop all queued packets. Currently the logic is triggered by incoming packets, so queued packets have to wait till another packet is arrived. It is done for simplicity since no additional locks or threads are required. For reliable protocols, a retransmission will kick it. For unreliable protocols, queued packets just seem like packet loss. Time-critical protocols might be broken, but they never work with queueing anyway. Signed-off-by: Chia-chi Yeh <chiachi@android.com>
