  • d4d5291c8   driver synchronization: make scsi_wait_scan more advanced ... Browse Code »

    There is currently only one way for userspace to say "wait for my storage
    device to get ready for the modules I just loaded": to load the
    scsi_wait_scan module. Expectations of userspace are that once this
    module is loaded, all the (storage) devices for which the drivers
    were loaded before the module load are present.

    Now, there are some issues with the implementation, and the async
    stuff got caught in the middle of this: The existing code only
    waits for the scsy async probing to finish, but it did not take
    into account at all that probing might not have begun yet.
    (Russell ran into this problem on his computer and the fix works for him)

    This patch fixes this more thoroughly than the previous "fix", which
    had some bad side effects (namely, for kernel code that wanted to wait for
    the scsi scan it would also do an async sync, which would deadlock if you did
    it from async context already.. there's a report about that on lkml):
    The patch makes the module first wait for all device driver probes, and then it
    will wait for the scsi parallel scan to finish.

    Fix lpfc_parse_bg_err()'s use of do_div(). It should be passing a 64-bit
    variable as the first parameter. However, since it's only using a 32-bit
    variable, it doesn't need to use do_div() at all, but can instead use the
    division operator.

    This deals with the following warnings:

    CC drivers/scsi/lpfc/lpfc_scsi.o
    drivers/scsi/lpfc/lpfc_scsi.c: In function 'lpfc_parse_bg_err':
    drivers/scsi/lpfc/lpfc_scsi.c:1397: warning: comparison of distinct pointer types lacks a cast
    drivers/scsi/lpfc/lpfc_scsi.c:1397: warning: right shift count >= width of type

  • e930438c4   Replace all DMA_nBIT_MASK macro with DMA_BIT_MASK(n) ... Browse Code »

    This is the second go through of the old DMA_nBIT_MASK macro,and there're not
    so many of them left,so I put them into one patch.I hope this is the last round.
    After this the definition of the old DMA_nBIT_MASK macro could be removed.

    89

    There is a race between resume from hibernation and the asynchronous
    scanning of SCSI devices and to prevent it from happening we need to
    call scsi_complete_async_scans() during resume from hibernation.

    In addition, if the resume from hibernation is userland-driven, it's
    better to wait for all device probes in the kernel to complete before
    attempting to open the resume device.
