s390/3270: correct size detection with the read-partition command

2014-07-16T08:48:10+00:00

The size detection for 3270 terminals with the read-partition command is
broken. The raw3270_reset_device_cb function clears the init_data array,
but if raw3270_writesf_readpart has been called the read-partition command
is queued which needs the init_data array. In this case the size detection
will fail and the invalid command does funny things to the terminal.

s390/ccwgroup: fix an uninitialized return code

2014-06-16T08:32:38+00:00

Since commit 0b60f9ead5d4816e7e3d6e28f4a0d22d4a1b2513
"s390: use device_remove_file_self() instead of device_schedule_callback()"
the return code of ccwgroup_ungroup_store is uninitialized. Make
sure the rc is always initialized.

s390/ccwgroup: obtain extra reference for asynchronous processing

2014-06-16T08:32:24+00:00

Commit 0b60f9ead5d4816e7e3d6e28f4a0d22d4a1b2513
"s390: use device_remove_file_self() instead of device_schedule_callback()"
changed ccwgroup to use an extra work queue instead of
device_schedule_callback. This function obtained an extra device
reference for its async work which is missing in the new implementation
and results in a "freeing memory with a lock still held" BUG. Fix
this by obtaining an extra reference for the async work.

s390/cio: set device name as early as possible

2014-06-16T08:31:03+00:00

Currently we set the device name at the time we call device_add after
we receive the interrupt for the first I/O. When something is not working
as expected during that first I/O (e.g. we don't receive an interrupt) we
print a message including the device name which has not yet been
initialized.

Set the device name after calling device_initialize (prior to starting
the first I/O) so that we have the name present if some unexpected error
occurs during that first I/O.
