[PATCH] Introduce FMODE_EXEC file flag

Introduce FMODE_EXEC file flag, to indicate that file is being opened for
execution.  This is useful for distributed filesystems to maintain
consistent behavior for returning ETXTBUSY when opening for write and
execution happens on different nodes.

akpm:

  Needed by Lustre at present.  I assume their objective to to work towards
  being able to install Lustre on an unmodified distro kernel, which seems
  sane.  It should have zero runtime cost.

  Trond and Chuck indicate that NFS4 can probably use this too, for the same
  thing.

  Steven says it's also on the GFS todo list.
