      target: pass sense_reason as a return value · de103c93
      由 Christoph Hellwig 提交于 
      Pass the sense reason as an explicit return value from the I/O submission
path instead of storing it in struct se_cmd and using negative return
values.  This cleans up a lot of the code pathes, and with the sparse
annotations for the new sense_reason_t type allows for much better
error checking.

      sense_reason_t with Roland's MODE SELECT changes)

      qla2xxx: Update target lookup session tables when a target session changes · c8292d1d
      由 Roland Dreier 提交于 
      It is possible for the target code to change the loop_id or s_id of a
target session in reaction to an FC fabric change.  However, the
session structures are stored in tables that are indexed by these two
keys, and if we just change the session structure but leave the
pointers to it in the old places in the table, havoc can ensue.  For
example, a new session might come along that should go in the old slot
in the table and overwrite the old session pointer.

To handle this, add a new tgt_ops->update_sess() method that also
updates the "by loop_id" and "by s_id" lookup tables when a session
changes, so that the keys where a session pointer is stored in these
tables always matches the keys in the session structure itself.

      tcm_qla2xxx: Format VPD page 83h SCSI name string according to SPC · c046aa0f
      由 Roland Dreier 提交于 
      My draft of SPC-4 says the following about the SCSI name string in
inquiry VPD page 83h:

    The SCSI NAME STRING field starts with either:

    a) the four UTF-8 characters 'eui.' concatenated with 16, 24, or
       32 hexadecimal digits (i.e., the UTF-8 characters 0 through 9
       and A through F) for an EUI-64 based identifier (see
       7.8.6.5). The first hexadecimal digit shall be the most
       significant four bits of the first byte (i.e., most significant
       byte) of the EUI-64 based identifier;
    b) the four UTF-8 characters 'naa.' concatenated with 16 or 32
       hexadecimal digits for an NAA identifier (see 7.8.6.6). The
       first hexadecimal digit shall be the most significant four bits
       of the first byte (i.e., most significant byte) of the NAA
       identifier; or
    c) the four UTF-8 characters 'iqn.' concatenated with an iSCSI
       Name for an iSCSI-name based identifier (see iSCSI).

However, the .tpg_get_wwn method for tcm_qla2xxx formats the WWN so
the SCSI name string looks like "52:4a:93:7d:24:5f:b2:12,t,0x0001".
This patch corrects the code so that VPD 83h gives a SPC-compliant
SCSI name string like "naa.524a937d245fb212,t,0x0001" while leavig
other uses alone (so configfs will still work with ':' separated WWNs).

      qla2xxx: Add missing ->vport_slock while calling qlt_update_vp_map · 29c08cda
      由 Nicholas Bellinger 提交于 
      All other callers of qlt_update_vp_map() already hold ->vport_slock
while updating the vp target map, so go ahead and add the missing
->vport_slock within qla24xx_disable_vp() code.

      SCSI: ARM: make fas216_dumpinfo function conditional · 48968177
      由 Arnd Bergmann 提交于 
      The fas216_dumpinfo function is only used by __fas216_checkmagic,
which is conditionally compiled, so we should put both functions
inside of the same #ifdef.

Without this patch, building rpc_defconfig results in:

drivers, which may or may not use the interrupt handler.
The oak variant doesn't, and should set the DONT_USE_INTR
