SET_RESTORE_SIGMASK(9)                    Driver Basics                    SET_RESTORE_SIGMASK(9)



NAME
       set_restore_sigmask - make sure saved_sigmask processing gets done

SYNOPSIS
       void set_restore_sigmask(void);

ARGUMENTS
       void
           no arguments

DESCRIPTION
       This sets TIF_RESTORE_SIGMASK and ensures that the arch signal code will run before
       returning to user mode, to process the flag. For all callers, TIF_SIGPENDING is already
       set or it's no harm to set it. TIF_RESTORE_SIGMASK need not be in the set of bits that the
       arch code will notice on return to user mode, in case those bits are scarce. We set
       TIF_SIGPENDING here to ensure that the arch signal code always gets run when
       TIF_RESTORE_SIGMASK is set.
