    [PATCH] const struct tty_operations · b68e31d0
    Jeff Dike authored
    As part of an SMP cleanliness pass over UML, I consted a bunch of
    structures in order to not have to document their locking.  One of these
    structures was a struct tty_operations.  In order to const it in UML
    without introducing compiler complaints, the declaration of
    tty_set_operations needs to be changed, and then all of its callers need to
    be fixed.
    This patch declares all struct tty_operations in the tree as const.  In all
    cases, they are static and used only as input to tty_set_operations.  As an
    extra check, I ran an i386 allyesconfig build which produced no extra
    53 drivers are affected.  I checked the history of a bunch of them, and in
    most cases, there have been only a handful of maintenance changes in the
    last six months.  serial_core.c was the busiest one that I looked at.
