mei: prevent unloading mei hw modules while the device is opened.

2015-07-23T04:31:05Z

chrdev_open() increases reference counter on cdev->owner. Instead of assigning the owner to mei subsystem, the owner has to be set to the underlaying HW module (mei_me or mei_txe), so once the device is opened the HW module cannot be unloaded.

mei: connection to fixed address clients from user-space

2015-05-24T18:13:48Z

This should be used for debug only. The feaure is gated by "allow_fixed_address" control exposed in debugfs. Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: add a reference from the host client to the me client

2015-05-24T18:13:10Z

Keep a pointer to associated me client in the host client object to eliminate me client searches. Check if the me client is active in the firmware by checking if its is linked on the me clients list Add accessors for the me client properties from host client.

mei: revamp client disconnection flow

2015-05-24T18:13:10Z

Split disconnected state into two parts first reception disconnect response from the firmware and second actually setting of disconnected state. Book keeping data are needed for processing and after firmware disconnected the client and are cleaned when setting the disconnected state in mei_cl_set_disconneted() function. Add mei_cl_send_disconnect to reduce code duplication. Signed-off-by: Tomas Winkler Signed-off-by: Alexander Usyskin Signed-off-by: Greg Kroah-Hartman

mei: replace check for connection instead of transitioning

2015-04-03T14:18:56Z

The function mei_cl_is_transitioning is just opposite of mei_cl_is_connected. What we actually wanted to check is if we lost connection so we can discard the check for transition and check for 'not connected' Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: use mei_cl_is_connected consistently

2015-04-03T14:18:56Z

Replace open coded check for cl->state !=/== MEI_FILE_CONNECTED with mei_cl_is_connected function. Note that cl->state != MEI_FILE_CONNECTED is not the same as cl->state == MEI_FILE_DISCONNECTED Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

fs: move struct kiocb to fs.h

struct kiocb now is a generic I/O container, so move it to fs.h. Also do a #include diet for aio.h while we're at it. Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro
