50/*
51 * The internal buffer is meant to store obaque blobs of data, so it doesn't
52 * know of higher level concepts like triggers.
53 * It consists of a number of pages that are used as a ringbuffer. Each data
54 * blob is stored in a simple record that consists of an integer, which
55 * contains the size of the following data, and the data bytes themselfes.
56 *
57 * To allow for multiple independent readers we create one internal buffer
58 * each time the device is opened and destroy the buffer when the file is
59 * closed again.
60 *
61 * One record can be written to a buffer by using the functions
62 * - dasd_eer_start_record (one time per record to write the size to the buffer
63 * and reserve the space for the data)
64 * - dasd_eer_write_buffer (one or more times per record to write the data)
65 * The data can be written in several steps but you will have to compute
66 * the total size up front for the invocation of dasd_eer_start_record.
67 * If the ringbuffer is full, dasd_eer_start_record will remove the required
68 * number of old records.
69 *
70 * A record is typically read in two steps, first read the integer that
71 * specifies the size of the following data, then read the data.
72 * Both can be done by
73 * - dasd_eer_read_buffer
74 *
75 * For all mentioned functions you need to get the bufferlock first and keep it
76 * until a complete record is written or read.
77 */

79
80/*
81 * Alle information necessary to keep track of an internal buffer is kept in
82 * a struct eerbuffer. The buffer specific to a file pointer is strored in
83 * the private_data field of that file. To be able to write data to all
84 * existing buffers, each buffer is also added to the bufferlist.
85 * If the user doesn't want to read a complete record in one go, we have to
86 * keep track of the rest of the record. residual stores the number of bytes
87 * that are still to deliver. If the rest of the record is invalidated between
88 * two reads then residual will be set to -1 so that the next read will fail.
89 * All entries in the eerbuffer structure are protected with the bufferlock.
90 * To avoid races between writing to a buffer on the one side and creating
91 * and destroying buffers on the other side, the bufferlock must also be used
92 * to protect the bufferlist.

347/*
348 * When a DASD device driver wants to report an error, it calls the
349 * function dasd_eer_write_trigger (via a notifier mechanism) and gives the
350 * respective trigger ID as parameter.
351 * Currently there are four kinds of triggers:
352 *
353 * DASD_EER_FATALERROR: all kinds of unrecoverable I/O problems
354 * DASD_EER_PPRCSUSPEND: PPRC was suspended
355 * DASD_EER_NOPATH: There is no path to the device left.
356 * DASD_EER_STATECHANGE: The state of the device has changed.
357 *
358 * For the first three triggers all required information can be supplied by
359 * the caller. For these triggers a record is written by the function
360 * dasd_eer_write_standard_trigger.
361 *
362 * When dasd_eer_write_trigger is called to write a DASD_EER_STATECHANGE
363 * trigger, we have to gather the necessary sense data first. We cannot queue
364 * the necessary SNSS (sense subsystem status) request immediatly, since we
365 * are likely to run in a deadlock situation. Instead, we schedule a
366 * work_struct that calls the function dasd_eer_sense_subsystem_status to
367 * create and start an SNSS request asynchronously.
368 *
369 * To avoid memory allocations at runtime, the necessary memory is allocated
370 * when the extended error reporting is enabled for a device (by
371 * dasd_eer_probe). There is one private eer data structure for each eer
372 * enabled DASD device. It contains memory for the work_struct, one SNSS cqr
373 * and a flags field that is used to coordinate the use of the cqr. The call
374 * to write a state change trigger can come in at any time, so we have one flag
375 * CQR_IN_USE that protects the cqr itself. When this flag indicates that the
376 * cqr is currently in use, dasd_eer_sense_subsystem_status cannot start a
377 * second request but sets the SNSS_REQUESTED flag instead.
378 *
379 * When the request is finished, the callback function dasd_eer_SNSS_cb
380 * is called. This function will invoke the function
381 * dasd_eer_write_SNSS_trigger to finally write the trigger. It will also
382 * check the SNSS_REQUESTED flag and if it is set it will call
383 * dasd_eer_sense_subsystem_status again.
384 *
385 * To avoid race conditions during the handling of the lock, the flags must
386 * be protected by the snsslock.
