  Hello,

  this patch set moves i_dquot array from struct inode into filesystem private
part of the inode. Thus filesystems which don't need it save 2 pointers in
their inodes (would be 3 after we add project quota support into generic
quota).

I have patches to move inode->i_data.private_list into filesystem private part
of the inode which is going to save another 2 pointers using the same
mechanism. However I didn't want to mix those in.

The patch series also contains a change to quotactl so that each filesystem
can set quota types it supports. This is in the end unrelated change
(originally it was necessary for i_dquot moving but in the end I changed
things so that it's not anymore). I can move that into a separate series
but I was somewhat reluctant to do that since that would mean another 6
one-line patches to the same files we are changing here...

Comments are welcome.
