      [PATCH] (25/25) more cleanups of struct gendisk. · e86a3786
      Alexander Viro authored
      	* we remove the paritition 0 from ->part[] and put the old
      contents of ->part[0] into gendisk itself; indexes are shifted, obviously.
      	* ->part is allocated at add_gendisk() time and freed at del_gendisk()
      according to value of ->minor_shift; static arrays of hd_struct are gone
      from drivers, ditto for manual allocations a-la ide.  As the matter of fact,
      none of the drivers know about struct hd_struct now.

      [PATCH] (24/25) disk capacity helpers · 3708de94
      Alexander Viro authored
      	new helpers - get_capacity(gendisk)/set_capacity(gendisk, sectors).
      Drivers switched to these; that eliminates most of the accesses to
      disk->part[]... in the drivers (and makes code more readable, while
      we are at it).  That had caught several bugs when minor had been
      used in place of minor>>minor_shift (acsi.c is especially nasty in
      that respect; I don't know if it had ever been used with multiple
      devices...)

      [PATCH] (23/25) move pointer to gendisk from hwif to drive · 07586b33
      Alexander Viro authored
      	 ide switched from hwif->gd[i] to hwif->drive[i]->disk - IOW, instead
      of array of two pointers to gendisks refered from hwif, we keep these pointers
      in relevant drives.  Cleaned up.

      	invalidate_buffers() pulled from cdrom ->reset() into its caller.
      At that point only cdrom.c using cdi->dev.  That will play a bit later.

      Alexander Viro authored
      	 pcd.c cleaned up, uses of cdi->dev eliminated, abuse of macros killed
      (it used to have
      #define PCD pcd[unit]
      #define PI PCD.pi
      and expected 'unit' to be local variable in each function that used these
      (== almost every function in there)).

      arguments; the first step in cleanup, they were monstrous).

      pointing to structure we neeed).  Cleaned up a bit.

      Alexander Viro authored
      	sbpcd.c - sigh... It used to have a global variable inventively called
      'd'.  Current disk number.  Tons of uses, 99% of them being D_S[d].<blah>.
      Added a new variable - current_drive.  Said animal is equal to D_S + d -
      it's reassigned at the same place as d.

      [PATCH] (12/25) sr.c passes pointers instead of minors now · 6f14c533

      	 killed passing minors around; we always pass a pointer to structure;
      scsi_CDs made static.  That killed uses of cdi->dev in sr.c and friends.

      	Global search'n'replace job - 'SCp' (Scsi_CD pointer - I'm not kidding;
      and yes, they spell it "Scsi") replaced with 'cd' (sr.c, sr_ioctl.c,
      sr_vendor.c).

      [PATCH] (10/25) sr.c device name handling · e342ff2e
      Alexander Viro authored
      	sr.c: we set SCp->cdi.name from the very beginning, which allows
      to kill passing minors in many cases (we can use "%s...", SCp->cd.name instead
      of "sr%d...", minor and that turns out to be the majority of places where
      we use minors at all).

      [PATCH] (9/25) update_partition() · 897c924e
      Alexander Viro authored
      	new helper - update_partition(disk, partition_number); does the
      right thing wrt devfs and driverfs (un)registration of partition entries.
      BLKPG ioctls fixed - now they call that beast rather than calling only
      devfs side.  New helper - rescan_partitions(disk, bdev); does all work
      with wiping/rereading/etc. and fs/block_dev.c now uses it instead of
      check_partition().  The latter became static.

      [PATCH] (8/25) Removing bogus arrays - ->de_arr[] · 06f55b09

      with its (single) element + flag.

      [PATCH] (7/25) Removing bogus arrays - ->part[].number · db09b5fc
      Alexander Viro authored
      	Each hd_struct used to have int number; in it.  It's used _only_
      in disk->part[0] - disk->part[n].number is never assigned/checked for any
      positive n.  Moved from hd_struct to gendisk (disk->part[0].number to
      disk->number).

      [PATCH] (6/25) Removing bogus arrays - ->driverfs_dev_arr[] · c5f45a70
      Alexander Viro authored
      	disk->driverfs_dev_arr is either NULL or consists of exactly one
      element.  Same change as above (struct device ** -> struct device *); old
      "is the pointer to array itself NULL or not?" replaced with a flag (in
      disk->flags).

      [PATCH] (5/25) Removing bogus arrays - ->flags[] · ab3bfaa2
      Alexander Viro authored
      	Seeing that now disk->flags[] always consists of one element, we
      replace char *flags with int flags, remove the junk from places that used
      to allocate these "arrays" and do obvious updates of the code
      (s/->flags[0]/->flags/).

      function isn't exported anymore.  Both it and driverfs_create_partitions()
      cleaned up.

      [PATCH] (3/25) Removing useless minor arguments · 36bd834b
      Alexander Viro authored
      	driverfs_remove_partitions(), devfs_register_partitions(),
      driverfs_create_partitions(), devfs_register_partition(), devfs_register_disc(),
      had lost 'minor' argument - it's always disk->first_minor these days.
      disk_name() takes partition number instead of minor now.  Callers of
      wipe_partitions() in fs/block_dev.c expanded.  Remaining caller passes
      gendisk instead of kdev_t now.

      [PATCH] (2/25) Removing ->nr_real · 4e493886
      Alexander Viro authored
      	Since ->nr_real is always 1 now, we can remove that field completely.
      Removed the last remnants of switch in disk_name() (it could be killed
      a long time ago, I just forgot to remove the last two cases when md and i2o
      got converted).  Collapsed several instances of
      disk->part[minor - disk->first_minor] - in cases when we know that we deal
      with disk->part[0].

      Alexander Viro authored
      	wipe_partitions() and driverfs_register_partitions(..., 1) (i.e.
      unregistering them) pulled into del_gendisk() and removed from callers.
      grok_partitions() merged with register_disk().  devfs_register_partitions(),
      grok_partitions() and wipe_partitions() not exported anymore.

      [PATCH] More ptrace fixes for 2.5.33 · 83d936cb
      Daniel Jacobowitz authored
      Here are the changes I have
      
        - Fix some bugs I introduced in zap_thread
        - Improve the check for traced children in sys_wait4
        - Fix parent links when using CLONE_PTRACE
      
      My thanks to OGAWA Hirofumi for pointing out the first bit.
      
      The only other issue I know of is something else Hirofumi pointed out
      earlier; there are problems when a tracing process dies unexpectedly.  I'll
      come back to that later.

      [PATCH] IDE cleanup (1.612) broke all fdisks I have... · c9581bb6
      Petr Vandrovec authored
      It is nice that blkdev_ioctl calls blk_ioctl itself, but unfortunately
      it does that only if driver's ioctl returns -EINVAL - and IDE returns
      -EIO :-(
      
      Patch below is tested for disks - I do not have IDE floppy nor IDE tape.

      This is the pid-max patch, the one i sent for 2.5.31 was botched.  I
      have removed the 'once' debugging stupidity - now PIDs start at 0 again.

      the declaration of 'DEFAULT_PID_MAX' which made it not compile ...

      [PATCH] ptrace-fix-2.5.33-A1 · ccfe3b20
      Ingo Molnar authored
      This contains Daniel's suggested fix that allows a parent to
      PTRACE_ATTACH to a child it forked.  That fixes the incorrect BUG_ON()
      assert that Ogawa's patch was intended to fix, and we thus undo Ogawa's
      patch.
      
      I've tested various ptrace uses and they appear to work just fine.
