Add a sysfs attribute 'size' which is the size of a vdisk device in bytes. Make the size of vdisk_nullio devices configurable. Accept "size" and "size_mb" as creation parameters for vdisk_nullio devices. Generate a CAPACITY DATA HAS CHANGED unit attention after size changes. Refuse any attempt to change the size into a number that is not a multiple of the block size.

The warning appears to be spurious - when LBDATA == PBDATA == 0, scst_ws_write_cmd_finished() will not use the uninitialized value saved by scst_ws_push_single_write().

However, the checks do not account for deferral of parsing to userland, as occurs when SCST_USER_PARSE_CALL or SCST_USER_PARSE_EXCEPTION are specified. In such cases the checks report errors on commands that userland has not yet had an opportunity to parse. NOTE: this includes a refactoring of the EXTRACHECKS to improve clarity. The rework is not exactly equivalent to the original code, but does conform to the comments describing the original code.

Under these conditions, most calls to local_irq functions should be replaced by no-ops. The CONFIG_PREEMPT_RT patch defines _nort versions of local_irq functions that compile away under CONFIG_PREEMPT_RT_FULL and compile to their "normal" equivalents otherwise. Define _nort equivalents to support compilation against both "normal" and RT-patched kernels, and use the _nort local_irq functons in cases where spinlocks are taken within a local_irq_save() or local_irq_disable() block. Without these changes, runtime warnings about "sleeping function called from invalid context" occur. Signed-off-by: Steven J.
