Re: 2.6.6-rc2-mm1

[raven]

Looks like there's no IDS defined for the Creator cards on sparc.

If only I could build a kernel on my little Ultra. Sigh.
I don't even have to fight the kids to use it.

In file included from drivers/char/drm/ffb_drv.c:336:
drivers/char/drm/drm_drv.h:545: error: `DRIVER_PCI_IDS' undeclared here 
(not in a function)

Re: 2.6.6-rc2-mm1

[raven]

This is a second attempt at a patch to address Christophs' concerns.

It assumes a 2.6.6-rc2-mm1 tree.

- renamed autofs4_may_umount to __may_umount_tree, made it static
  and moved it to namespace.c.
- added stub function may_umount_tree with description
- altered may_umount to use above stub function and added
  little description
- added may_umount_tree prototype to fs.h
- removed the EXPORT_SYMBOL for vfsmount_lock
- updated expire.c to suit

Andrew,

This is the entire patch again. I hope this won't cause to much 
hastle.

Sorry for changing my opionin, but I somehow thought autofs3 could make
more use of this function.  it it's really just a single atomic_read that's
shared it doesn't really make a lot of sense, does it?

That's right.

autofs3 requires it to behave as per the little description I put in.

So is the first version what we want?
Should I do a patch which reverts it or should I do a new patch that 
adds the prototype I originally missed?

Be good to clear up what I need to do before I spend more time on it.

It's say keep may_umount as is, and do a no-argument may_umount_tree
in namespace.c aswell.  As for what patches is best ask akpm.

Incremental patch to revert previous may_umount_tree patch based on 
Christophs' further observation.

The drivers/char/drm/drm_irq.h in this patch contains a
  #define __NO_VERSION__
which is useless since ages.

The patch below removes it.

Please apply
