  • ba6d10ab8   Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi ... Browse Code »

    Pull SCSI updates from James Bottomley:
    "This is mostly update of the usual drivers: qla2xxx, hpsa, lpfc, ufs,
    mpt3sas, ibmvscsi, megaraid_sas, bnx2fc and hisi_sas as well as the
    removal of the osst driver (I heard from Willem privately that he
    would like the driver removed because all his test hardware has
    failed). Plus number of minor changes, spelling fixes and other
    trivia.

    The big merge conflict this time around is the SPDX licence tags.
    Following discussion on linux-next, we believe our version to be more
    accurate than the one in the tree, so the resolution is to take our
    version for all the SPDX conflicts"

    Note on the SPDX license tag conversion conflicts: the SCSI tree had
    done its own SPDX conversion, which in some cases conflicted with the
    treewide ones done by Thomas & co.

    In almost all cases, the conflicts were purely syntactic: the SCSI tree
    used the old-style SPDX tags ("GPL-2.0" and "GPL-2.0+") while the
    treewide conversion had used the new-style ones ("GPL-2.0-only" and
    "GPL-2.0-or-later").

    In these cases I picked the new-style one.

    In a few cases, the SPDX conversion was actually different, though. As
    explained by James above, and in more detail in a pre-pull-request
    thread:

    "The other problem is actually substantive: In the libsas code Luben
    Tuikov originally specified gpl 2.0 only by dint of stating:

    * This file is licensed under GPLv2.

    In all the libsas files, but then muddied the water by quoting GPLv2
    verbatim (which includes the or later than language). So for these
    files Christoph did the conversion to v2 only SPDX tags and Thomas
    converted to v2 or later tags"

    So in those cases, where the spdx tag substantially mattered, I took the
    SCSI tree conversion of it, but then also took the opportunity to turn
    the old-style "GPL-2.0" into a new-style "GPL-2.0-only" tag.

    Similarly, when there were whitespace differences or other differences
    to the comments around the copyright notices, I took the version from
    the SCSI tree as being the more specific conversion.

    Finally, in the spdx conversions that had no conflicts (because the
    treewide ones hadn't been done for those files), I just took the SCSI
    tree version as-is, even if it was old-style. The old-style conversions
    are perfectly valid, even if the "-only" and "-or-later" versions are
    perhaps more descriptive.

  • 5da1faa07   scsi: wd719x: Fix resets and aborts ... Browse Code »

    Host reset oopses because it calls wd719x_chip_init, which calls
    request_firmware, under a spinlock. Stop the RISC first, then flush active
    SCBs under a spinlock. Finally call wd719x_chip_init unlocked.

    Also found and fixed more bugs during tests:

    Affected active SCBs were not flushed during abort, bus and device
    reset. This caused problems in a following host reset (hang or oops).

    Device and bus reset failed under load because the result of the reset
    command is WD719X_SUE_TERM or WD719X_SUE_RESET. Don't treat these codes as
    error in wd719x_wait_done.

    wd719x_direct_cmd for RESET/ABORT commands didn't work properly, causing
    timeouts. Looks like it was caused by the WD719X_DISABLE_INT bit. Not
    setting it for RESET/ABORT commands seems to fix the probem. Also lower
    the log level of the corresponding "direct command completed" message to
    debug.

    Unfortunately, my documentation is missing some pages, including page
    67 (SPIDER67.gif) about resets :(

  • 09c434b8a   treewide: Add SPDX license identifier for more missed files ... Browse Code »

    Add SPDX license identifiers to all files which:

    - Have no license information of any form

    - Have MODULE_LICENCE("GPL*") inside which was used in the initial
    scan/conversion to ignore the file

    These files fall under the project license, GPL v2 only. The resulting SPDX
    license identifier is:

    GPL-2.0-only

  • 2a3d4eb8e   scsi: flip the default on use_clustering ... Browse Code »

    Most SCSI drivers want to enable "clustering", that is merging of
    segments so that they might span more than a single page. Remove the
    ENABLE_CLUSTERING define, and require drivers to explicitly set
    DISABLE_CLUSTERING to disable this feature.

    Don't populate the read-only array card_types on the stack but instead
    make it static and constify it. Makes the object code smaller by over
    110 bytes:

  • 2ecf8e0ae   wd719x: add missing .module to wd719x_template ... Browse Code »

    wd719x_template is missing the .module field, causing module refcount
    not to work, allowing to rmmod the driver while in use (mounted filesystem),
    causing an oops.

    Set .module to THIS_MODULE to fix the problem.
