    Subject[PATCH 00/41] signal: Use set_current_blocked()
    Date
    From: Matt Fleming <matt.fleming@intel.com>

    Hi Oleg,

    I did a tree wide scan of all the code that modifies current->blocked
    without using the set_current_blocked() accessor. This patch series is
    the result of the conversion to the new accessor functions.

    This series also helps to reduce the complexity of my signal
    scalability patches that I posted in April, because we now have much
    fewer callers of recalc_sigpending() (the signal scalability patches
    introduce a new lock that needs to be held when calling
    recalc_sigpending()).

    This series is available in the 'oleg/set-current-blocked' branch at,

    git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/linux-2.6.git

    P.S I've punted on fully converting ia64 to set_current_blocked()
    because bits of the signal code are written in asm. I'll follow up
    with a later patch that does the conversion once I've improved my ia64
    foo (or coerced Tony Luck into doing it ;).
