  • 45e79a3ac   bsg: add a request_queue argument to scsi_cmd_ioctl() ... Browse Code »

    bsg uses scsi_cmd_ioctl() for some SCSI/sg ioctl
    commands. scsi_cmd_ioctl() gets a request queue from a gendisk
    arguement. This prevents bsg being bound to SCSI devices that don't
    have a gendisk (like OSD). This adds a request_queue argument to
    scsi_cmd_ioctl(). The SCSI/sg ioctl commands doesn't use a gendisk so
    it's safe for any SCSI devices to use scsi_cmd_ioctl().

    Remove the destroy_dirty_buffers argument from invalidate_bdev(), it hasn't
    been used in 6 years (so akpm says).

    find * -name \*.[ch] | xargs grep -l invalidate_bdev |
    while read file; do
    quilt add $file;
    sed -ie 's/invalidate_bdev(\([^,]*\),[^)]*)/invalidate_bdev(\1)/g' $file;

  • 0b4d41471   [PATCH] sysctl: remove insert_at_head from register_sysctl ... Browse Code »

    The semantic effect of insert_at_head is that it would allow new registered
    sysctl entries to override existing sysctl entries of the same name. Which is
    pain for caching and the proc interface never implemented.

    I have done an audit and discovered that none of the current users of
    register_sysctl care as (excpet for directories) they do not register
    duplicate sysctl entries.

    So this patch simply removes the support for overriding existing entries in
    the sys_sysctl interface since no one uses it or cares and it makes future
    enhancments harder.

  • 4b998d4f6   [PATCH] sysctl: cdrom: don't set de->owner ... Browse Code »

    There is no need for open files in /proc/sys/XXX to hold a reference count on
    the module that provides the file to prevent module unload races. While there
    is code active in the module p->used in the sysctl_table_header is
    incremented, preventing the sysctl from being unregisted. Once the sysctl is
    unregistered it cannot be found. Open files are also not a problem as they
    revalidate the sysctl information and bump p->used before accessing module
    code.

    So setting de->owner is unnecessary, makes for a bad example and gets in my
    way of removing ctl_table->de.

  • 2e11c207b   [PATCH] cdrom: set default timeout to 7 seconds ... Browse Code »

    It's a known fact that Windows times out commands after 7 seconds, so
    drives generally try and respond if they can before that happens. We
    default to 5 seconds, which sometimes is a bit too short.

    Jeremy Higdon reported here:

    http://lkml.org/lkml/2007/1/1/145

    that his drive takes longer than 5 seconds for a "read track
    information" command, later confirming that it is about 6.7 seconds.

    So just do the sane thing and change the default command timeout to 7
    seconds to avoid other surprises.

  • 8e5cfc45e   [PATCH] Fixup blk_rq_unmap_user() API ... Browse Code »

    The blk_rq_unmap_user() API is not very nice. It expects the caller to
    know that rq->bio has to be reset to the original bio, and it will
    silently do nothing if that is not done. Instead make it explicit that
    we need to pass in the first bio, by expecting a bio argument.

  • 5cbded585   [PATCH] getting rid of all casts of k[cmz]alloc() calls ... Browse Code »

    Run this:

    #!/bin/sh
    for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
    echo "De-casting $f..."
    perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
    done

    And then go through and reinstate those cases where code is casting pointers
    to non-pointers.

    And then drop a few hunks which conflicted with outstanding work.

  • 4aff5e233   [PATCH] Split struct request ->flags into two parts ... Browse Code »

    Right now ->flags is a bit of a mess: some are request types, and
    others are just modifiers. Clean this up by splitting it into
    ->cmd_type and ->cmd_flags. This allows introduction of generic
    Linux block message types, useful for sending generic Linux commands
    to block devices.

  • 16070428d   [PATCH] fix cdrom open ... Browse Code »

    Some time ago the cdrom open routine was changed so that we call the
    driver's open routine before checking to see if it is read only. However,
    if we discovered that a read write open was not possible and the open
    flags required a writable open, we just returned -EROFS without calling
    the driver's release routine. This seems to work for most cdrom drivers,
    but breaks the Powerpc iSeries virtual cdrom rather badly.

    This just inserts the release call in the error path to balance the call
    to "->open()" done by "open_for_data()".

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
