[PATCH] Initial support for struct vfs_cred [0/1]

[Trond Myklebust]

Hi Linus,

  I hope this addresses all the issues that you raised (minus
user_struct, as I explained). Changes w.r.t.  previous patches are as
follows:

  1) Dropped current_fsuid(), current_fsgid(), current_ngroups().
     => had to merge patches [1/3] & [3/3]. Makes for a rather large
     initial patch (see diffstat output below) 8-(

  2) 'struct ucred' renamed to 'struct vfs_cred'. Renamed the
     helper routines to reflect the new struct name.

  3) Moved #ifdef __KERNEL__

  4) Renamed the remaining current_* routines so as to drop the
     'current_' prefix where appropriate (e.g. setfsuid() instead of
     current_setfsuid(), ...).
     Hopefully the naming scheme will be seen as an improvement.

  5) Dropped patch [2/3]. There is no longer a namespace conflict
     to justify renaming the networking code's 'struct ucred'.

Cheers,
  Trond
