Bump up version number, skip "4.6.0" because this might
clash with zfcp version in certain distros.Signed-off-by: Andreas Herrmann
Signed-off-by: James Bottomley -
If zfcp's port erp fails we now call fc_remote_port_delete. This helps
to avoid offlined scsi devices if scsi commands time out due to path
failures. When an adapter erp fails we call fc_remote_port_delete for
all ports on that adapter.Signed-off-by: Andreas Herrmann

This patch changes several mempool users, all of which are basically just
wrappers around kmalloc(), to use the common mempool_kmalloc/kfree, rather
than their own wrapper function, removing a bunch of duplicated code.Signed-off-by: Matthew Dobson

The patch fixes following issues:
(1) Replace scsi_add_device with scsi_scan_target.
(Thus the rport instead of the scsi_host becomes parent of a
scsi_target again.)(2) Avoid scsi_device allocation during registration of an remote port.
(Would be done during fc_scsi_scan_rport.)(3) Fix queuecommand behaviour when an zfcp unit is blocked.
(Call scsi_done with DID_NO_CONNECT instead of returning
SCSI_MLQUEUE_DEVICE_BUSY otherwise we might end up waiting
for completion in blk_execute_rq for ever.)Signed-off-by: Andreas Herrmann

It fixes a bug in zfcp which provokes a race
in scsi_scan.c. Finally this can lead to an Oops like:kernel BUG at fs/sysfs/symlink.c:87!
Correctly set this_id for the host. Otherwise we provoke
a race between scsi_target_reap_work and concurrent
scsi_add_device.Signed-off-by: Andreas Herrmann

Replaced zfcp adapter attributes with fc_host attributes:
fc_topology by port_type, physical_wwpn by permanent_port_name.
Make use of fc_host attribute supported_speeds.
Removed zfcp adapter attribute physical_s_id.Signed-off-by: Andreas Herrmann
Signed-off-by: James Bottomley -
Added host stats, removed superfluous get_starget_ functions,
removed some attributes from zfcp specific sysfs tree (e.g.
scsi_host_no, scsi_lun, wwnn and d_id).
Host stats are given for the physical adapter port not for the
virtual adapter. Reset stats is implemented in the device driver.Signed-off-by: Andreas Herrmann

Fixed various problems in opening sequence of adapters which was previously
changed with NPIV support:
o corrected handling when exchange port data function is not supported,
otherwise adapters on z900 cannot be opened anymore
o corrected setup of timer for exchange port data if called from error
recovery
o corrected check of return code of exchange config dataSigned-off-by: Andreas Herrmann

Move initialization of locks and lists to adapter allocation function.

- added typedef unsigned int __nocast gfp_t;
- replaced __nocast uses for gfp flags with gfp_t - it gives exactly
the same warnings as far as sparse is concerned, doesn't change
generated code (from gcc point of view we replaced unsigned int with
typedef) and documents what's going on far better.Signed-off-by: Al Viro

this patch adds some fc host attributes and removes its equivalents
from the zfcp_adapter structure and zfcp specific sysfs subtree.Furthermore it removes superfluous calls to fc_remort_port_delete when
an adapter is set offline because rports will be removed by
fc_remove_host anyway.Signed-off-by: Andreas Herrmann

N_Port ID Virtualization (NPIV) allows a single FCP port to appear as
multiple, distinct ports providing separate port identification. NPIV
is supported by FC HBAs on System z9. zfcp was adapted to support this

Debug features (DBFs) els_dbf, cmd_dbf and abt_dbf were removed and
san_dbf, hba_dbf and scsi_dbf were introduced. The erp_dbf did not
change.
The new traces improve debugging of problems with zfcp, scsi-stack,
multipath and hardware in the SAN. san_dbf traces things like ELS and
CT commands, hba_dbf saves HBA specific information of requests, and
scsi_dbf saves FCP and SCSI specific information of requests. Common
to all new DBFs is that they provide a so called structured view. This
significantly improves readability of the traces.Signed-off-by: Andreas Herrmann

o union zfcp_req_data removed
o increment unit refcount when processing FCP commands
(This fixes a theoretical race: When all scsi commands of a unit
are aborted and the scsi_device is removed then the unit could be
removed before all fsf_requests of that unit are completely processed.)Signed-off-by: Andreas Herrmann
