  • 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

  • 323edb2e2   watchdog: constify watchdog_ops and watchdog_info structures ... Browse Code »

    These watchdog_ops and watchdog_info structures are only stored
    in the ops and info fields of a watchdog_device structure,
    respectively, which are const. Thus make the watchdog_ops and
    watchdog_info structures const as well.

    Done with the help of Coccinelle. The rules for the watchdog_ops case are
    as follows:

    //
    @r disable optional_qualifier@
    identifier i;
    position p;
    @@
    static struct watchdog_ops i@p = { ... };

    @ok@
    identifier r.i;
    struct watchdog_device e;
    position p;
    @@
    e.ops = &i@p;

    @bad@
    position p != {r.p,ok.p};
    identifier r.i;
    struct watchdog_ops e;
    @@
    e@i@p

    @depends on !bad disable optional_qualifier@
    identifier r.i;
    @@
    static
    +const
    struct watchdog_ops i = { ... };

  • b893e344b   watchdog: constify watchdog_ops structures ... Browse Code »

    Declare watchdog_ops structures as const as they are only stored in the
    ops field of a watchdog_device structure. This field is of type const, so
    watchdog_ops structures having this property can be made const too.
    Done using Coccinelle:

    @r disable optional_qualifier@
    identifier x;
    position p;
    @@
    static struct watchdog_ops x@p={...};

    @ok@
    struct watchdog_device w;
    identifier r.x;
    position p;
    @@
    w.ops=&x@p;

    @bad@
    position p != {r.p,ok.p};
    identifier r.x;
    @@
    x@p

    @depends on !bad disable optional_qualifier@
    identifier r.x;
    @@

  • b2527d200   s390/watchdog: support for KVM hypervisors and delete pr_info messages ... Browse Code »

    This patch extends the diag288 watchdog driver to be able to deal with KVM
    hypervisors. Only z/VM needs special handling, we can use the same interface
    as on LPAR. Remove all pr_info output to avoid misconception. Because there
    is no value in these messages and only the pr_err messages make sense.

  • 9ec6cb80c   s390/watchdog: enable KEEPALIVE for /dev/watchdog ... Browse Code »

    There's no reason why we wouldn't want to be able to send a keep alive
    message to /dev/watchdog (feed dog) for the s390 diag288 watchdog, so
    let's enable the WDIOF_KEEPALIVEPING option.
