[PATCH v2 0/3] staging: comedi: avoid mixing __user and kernel pointers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Some patches from the v1 sequence of 9 patches that were nothing to do
with mixing __user and kernel pointers have already been applied by
Greg, leaving 4 patches unapplied.  For v2, I've combined 2 of those 4
patches, reordered them, slightly modified one of them and changed the
commit messages.

Patch 1 in v2 corresponds to patch 4 in v1.  Patch 2 in v2 corresponds
to patch 9 in v1.  Patch 3 in v2 corresponds to patches 1 and 2 in v1.

I should point out that Dan Carpenter objected to this change in v1 and
nothing has been done to address that in v2.  It's a difference of
opinion.

As remarked in the original patch sequence, one of these patches (patch
2 this time) contains a couple of overlength lines in "pcmmio.c" and
"pcmuio.c" as the affected functions need a serious amount of
refactoring.  At least the patched lines are slightly shorter than the
originals!

Patch 1) staging: comedi: add chanlist to do_cmdtest() handlers
Patch 2) staging: comedi: put command channel list in async structure
Patch 3) staging: comedi: add __user tag to chanlist
