      [PATCH] Split struct request ->flags into two parts · 4aff5e23
      由 Jens Axboe 提交于 
      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.

      [PATCH] lockdep: floppy.c irq release fix · 3e541a4a
      由 Ingo Molnar 提交于 
      The lock validator triggered a number of bugs in the floppy driver, all
related to the floppy driver allocating and freeing irq and dma resources from
interrupt context.  The initial solution was to use schedule_work() to push
this into process context, but this caused further problems: for example the
current floppy driver in -mm2 is totally broken and all floppy commands time
out with an error.  (as reported by Barry K.  Nathan)

This patch tries another solution: simply get rid of all that dynamic IRQ and
DMA allocation/freeing.  I doubt it made much sense back in the heydays of
floppies (if two devices raced for DMA or IRQ resources then we didnt handle
those cases too gracefully anyway), and today it makes near zero sense.

So the new code does the simplest and most straightforward thing: allocate IRQ
and DMA resources at module init time, and free them at module removal time.
Dont try to release while the driver is operational.  This, besides making the
floppy driver functional again has an added bonus, floppy IRQ stats are
finally persistent and visible in /proc/interrupts:

  6: 63 XT-PIC-level floppy

Besides normal floppy IO i have also tested IO error handling, motor-off
timeouts, etc.  - and everything seems to be working fine.

      [PATCH] drivers/block: Use ARRAY_SIZE macro · 945f390f
      由 Tobias Klauser 提交于 
      Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]) and remove a
duplicate of ARRAY_SIZE. Some trailing whitespaces are also removed.

drivers/block/acsi* has been left out as it's marked BROKEN.

      [PATCH] Add block_device_operations.getgeo block device method · a885c8c4
      由 Christoph Hellwig 提交于 
      HDIO_GETGEO is implemented in most block drivers, and all of them have to
duplicate the code to copy the structure to userspace, as well as getting
the start sector.  This patch moves that to common code [1] and adds a
->getgeo method to fill out the raw kernel hd_geometry structure.  For many
drivers this means ->ioctl can go away now.

[1] the s390 block drivers are odd in this respect.  xpram sets ->start
    to 4 always which seems more than odd, and the dasd driver shifts
    the start offset around, probably because of it's non-standard
    sector size.

      [BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn() · 8ffdc655
      由 Tejun Heo 提交于 
      add @uptodate argument to end_that_request_last() and @error
to rq_end_io_fn().  there's no generic way to pass error code
to request completion function, making generic error handling
of non-fs request difficult (rq->errors is driver-specific and
each driver uses it differently).  this patch adds @uptodate
to end_that_request_last() and @error to rq_end_io_fn().

for fs requests, this doesn't really matter, so just using the
same uptodate argument used in the last call to
end_that_request_first() should suffice.  imho, this can also
help the generic command-carrying request jens is working on.

      Linux-2.6.12-rc2 · 1da177e4
      由 Linus Torvalds 提交于 
      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!
