Subject: [PATCHSET 2/3 blk-for-2.6.28] block: implement extended devt, take #3
Newsgroups: gmane.linux.ide
Date: Monday 25th August 2008 10:47:16 UTC (over 9 years ago)
Hello, all.

This is the third take of block-extended-devt patchset and contains
the following 10 patches.

0001-block-misc-updates.patch
0002-block-make-variable-and-argument-names-more-consist.patch
0003-block-don-t-depend-on-consecutive-minor-space.patch
0004-block-fix-disk-part-dereferencing-race.patch
0005-block-fix-diskstats-access.patch
0006-block-implement-extended-dev-numbers.patch
0007-block-adjust-formatting-for-large-minors-and-add-ex.patch
0008-sd-ide-disk-apply-extended-minors-to-sd-and-ide.patch
0009-block-implement-CONFIG_DEBUG_BLOCK_EXT_DEVT.patch

0001-0002 are trivial preparation patches.  0003 implements accessors
and applies them to insulate consecutive device number assumption and
help fixing partition dereferencing problem.  0004-0005 fixes
partition dereferencing bug and simplifies stats handling.  0006-0009
implement and apply extended devt.

Changes from the last take[L] are...

* Adapted to blk-for-2.6.28. 
* 0005 and 0006 of the last take are collapsed into 0005.
* Reverse iteration bug fixed.
* blk_alloc_devt() fixed to honor first_minor when allocating from
  consecutive minor range.

For general description of the patchset, please read description of
the first take[F].

This patchset is against...
