Sure, I will use set_current_blocked().

While we are here, do you suggest I re-use current->saved_sigmask and
hence use set_restore_sigmask() while resetting the sigmask?

I see saved_sigmask being used just before task sleeps and restored when
task is scheduled back. So I dont see a case where using saved_sigmask
in uprobes could conflict with its current usage.

However if you prefer we use a different sigmask to save and restore, I
can make it part of the utask structure.

Thanks and Regards
