* MMC: OMAP: Move failing command abortion to workqueueJarkko Lavinen2008-04-18
| | | | | | | | Abort failed command from workqueue rather than from an interrupt, allowing longer delays in abortion. Signed-off-by: Jarkko Lavinen <jarkko.lavinen@nokia.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* MMC: OMAP: Use tasklet instead of workqueue for cover switch notificationJarkko Lavinen2008-04-18
| | | | | | | | | | | | | The cover waitqueue is occasionally scheduled twice from timer and the interrupt and oops follows. It would have been possible to fix this problem with spinlocks but using tasklet was a dropin solution with no need for locking. This path also adds some cleanups.

* MMC: OMAP: Abort stuck commandsJarkko Lavinen2008-04-18
| | | | | | | | | | | | | | When a card is removed while it is being accessed, a command can get stuck so that no timeout or end of command interrupt ever occurs. The command getting stuck is almost always CDM12, but also the other commands can get stuck. Catch a stuck command with a timer and try sending the initialization stream until the controller starts running again and responds with the end of command status.

| * ocfs2/cluster: Get rid of arguments to the timeout routinesJeff Mahoney2008-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | We keep seeing bug reports related to NULL pointer derefs in o2net_set_nn_state(). When I originally wrote up the configurable timeout patch, I had tried to plan for multiple clusters. This was silly. The timeout routines all use o2nm_single_cluster so there's no point in passing an argument at all. This patch removes the arguments and kills those bugs dead.

| | | | | | | | | | | | | | | | | | | | Inode allocation is modified to look in other nodes allocators during extreme out of space situations.

In ocfs2_merge_rec_right, when we find the merge extent is "CONTIG_LEFT" with the last extent record of the previous extent block, we will merge it to the prevoius extent block and change all the related extent blocks accordingly. As for CONTIG_LEFTRIGHT, we will handle CONTIG_RIGHT first so that when the index is zero, the merge process will be more efficient and easier.

| | | | | | | | | | | | | | | | | | | | | | | | /sys/fs is where we really want file system specific sysfs objects. Ocfs2-tools has been updated to look in /sys/fs/o2cb. We can maintain backwards compatibility with old ocfs2-tools by using a sysfs symlink. After some time (2 years), the symlink can be safely removed.

| * ocfs2: Reconnect after idle time out.Tao Ma2008-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, o2net connects to a node on hb_up and disconnects on hb_down and net timeout. It disconnects on net timeout is ok, but it should attempt to reconnect back. This is because sometimes nodes get overloaded enough that the network connection breaks but the disk hb does not. And if we get into that situation, we either fence (unnecessarily) or wait for its disk hb to die (and sometimes hang in the process). So in this updated scheme, when the network disconnects, we keep attempting to reconnect till we succeed or we get a disk hb down event. If the other node is really dead, then we will eventually get a node down event. If not, we should be able to connect again and continue.
