  • 21b2f0c80   [SCSI] unify SCSI_IOCTL_SEND_COMMAND implementations ... Browse Code »

    We currently have two implementations of this obsolete ioctl, one in
    the block layer and one in the scsi code. Both of them have drawbacks.

    This patch kills the scsi layer version after updating the block version
    with the missing bits:

    - argument checking
    - use scatterlist I/O
    - set number of retries based on the submitted command

    This is the last user of non-S/G I/O except for the gdth driver, so
    getting this in ASAP and through the scsi tree would be nie to kill
    the non-S/G I/O path. Jens, what do you think about adding a check
    for non-S/G I/O in the midlayer?

    Thanks to Or Gerlitz for testing this patch.

  • 88b9adb07   [PATCH] config: fix CONFIG_LFS option ... Browse Code »

    The help text says that if you select CONFIG_LBD, then it will automatically
    select CONFIG_LFS. That isn't currently the case, so update the text.

    - Get rid of the cruft in the help text mentioning CONFIG_LBD

    - Tell unsure users to select CONFIG_LFS.

    - Remove the `default n'.

  • 9b41046cd   [PATCH] Don't pass boot parameters to argv_init[] ... Browse Code »

    The boot cmdline is parsed in parse_early_param() and
    parse_args(,unknown_bootoption).

    And __setup() is used in obsolete_checksetup().

    start_kernel()
    -> parse_args()
    -> unknown_bootoption()
    -> obsolete_checksetup()

    If __setup()'s callback (->setup_func()) returns 1 in
    obsolete_checksetup(), obsolete_checksetup() thinks a parameter was
    handled.

    If ->setup_func() returns 0, obsolete_checksetup() tries other
    ->setup_func(). If all ->setup_func() that matched a parameter returns 0,
    a parameter is seted to argv_init[].

    Then, when runing /sbin/init or init=app, argv_init[] is passed to the app.
    If the app doesn't ignore those arguments, it will warning and exit.

    This patch fixes a wrong usage of it, however fixes obvious one only.

  • 68eef3b47   [PATCH] Simplify proc/devices and fix early termination regression ... Browse Code »

    Make baby-simple the code for /proc/devices. Based on the proven design
    for /proc/interrupts.

    This also fixes the early-termination regression 2.6.16 introduced, as
    demonstrated by:

    # dd if=/proc/devices bs=1
    Character devices:
    1 mem
    27+0 records in
    27+0 records out

    This should also work (but is untested) when /proc/devices >4096 bytes,
    which I believe is what the original 2.6.16 rewrite fixed.

  • 837c78787   [BLOCK] increase size of disk stat counters ... Browse Code »

    The kernel's representation of the disk statistics uses the type unsigned
    which is 32b on both 32b and 64b platforms. Unfortunately, most system
    tools that work with these numbers that are exported in /proc/diskstats
    including iostat read these numbers into unsigned longs. This works fine
    on 32b platforms and when the number of IO transactions are small on 64b
    platforms. However, when the numbers wrap on 64b platforms & you read the
    numbers into unsigned longs, and compare the numbers to previous readings,
    then you get an unsigned representation of a negative number. This looks
    like a very large 64b number & gives you bizarre readouts in iostat:

    ilc4: Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util
    ilc4: sda 5.50 0.00 143.96 0.00 307496983987862656.00 0.00 153748491993931328.00 0.00 2136028725038430.00 7.94 55.12 5.59 80.42

    Though fixing iostat in user space is possible, and a quick survey
    indicates that several other similar tools also use unsigned longs when
    processing /proc/diskstats. Therefore, it seems like a better approach
    would be to extend the length of the disk_stats structure on 64b
    architectures to 64b. The following patch does that. It should not affect
    the operation on 32b platforms.

    Add blkcnt_t as the type of inode.i_blocks. This enables you to make the size
    of blkcnt_t either 4 bytes or 8 bytes on 32 bits architecture with CONFIG_LSF.

    - CONFIG_LSF
    Add new configuration parameter.
    - blkcnt_t
    On h8300, i386, mips, powerpc, s390 and sh that define sector_t,
    blkcnt_t is defined as u64 if CONFIG_LSF is enabled; otherwise it is
    defined as unsigned long.
    On other architectures, it is defined as unsigned long.
    - inode.i_blocks
    Change the type from sector_t to blkcnt_t.
