If a failed command is retried and fails again we need
to enter SCSI EH, otherwise we will never be able to

To detect this situation we must not clear scmd->eh_eflags
when EH finishes but rather make it persistent throughout

sas_ata_strategy_handler() adds the works of the ata error handler to
system_unbound_wq. This workqueue asynchronously runs work items, so the
ata error handler will be performed concurrently on different CPUs. In
this case, ->host_failed will be decreased simultaneously in
scsi_eh_finish_cmd() on different CPUs, and become abnormal.It will lead to permanently inequality between ->host_failed and
->host_busy, and scsi error handler thread won't start running. IO
errors after that won't be handled.Since all scmds must have been handled in the strategy handler, just
remove the decrement in scsi_eh_finish_cmd() and zero ->host_busy after
the strategy handler to fix this race.Fixes: 50824d6c5657 ("[SCSI] libsas: async ata-eh")

Change the MTMKPART operation of the MTIOCTOP ioctl so that it works
also with current drives (LTO-5/6, etc.). Send a separate FORMAT MEDIUM
command if the partition mode page indicates that this is required. Use
LOAD to position the tape at the beginning of tape.The operation is extended so that if the argument is negative, its
absolute value specifies the size of partition 0, which is the
physically first partition of the tape.Signed-off-by: Kai Mäkisara

Change st driver to allow enabling or disabling debug output
via sysfs file /sys/bus/scsi/drivers/st/debug_flag.Previously the only way to enable debug output was:
1. loading the driver with the module parameter debug_flag=1
2. an ioctl call (this method was also the only way to dynamically
disable debug output).To use the ioctl you need a second tape drive (if you are
actively testing the first tape drive) since a second process
cannot open the first tape drive if it is in use.The this change is only functional if the value of the macro
DEBUG in st.c is a non-zero value (which it is by default).Signed-off-by: Shane Seymour

This patch implements tape statistics in the st module via
sysfs. Current no statistics are available for tape I/O and there
is no easy way to reuse the block layer statistics for tape
as tape is a character device and does not have perform I/O in
sector sized chunks (the size of the data written to tape
can change). For tapes we also need extra stats related to
things like tape movement (via other I/O).There have been multiple end users requesting statistics
including AT&T (and some HP customers who have not given
permission to be named). It is impossible for them
to investigate any issues related to tape performance
in a non-invasive way.[jejb: eliminate PRId64]
