um: simplify set_handler() · e87df986

Al Viro authored Aug 18, 2011



For one thing, we always block the same signals (IRQ ones - IO, WINCH, VTALRM),
so there's no need to pass sa_mask elements in arguments.  For another, the
flags depend only on whether it's an IRQ signal or not (we add SA_RESTART
for them).

um: series of __get_user() is costly in sigframe handling · a955bd61

Al Viro authored Aug 18, 2011



It's not x86, where __get_user() is a single dereference; here it's
a single ptrace(2) call in host, which obviously costs a lot more.
IOW, it's cheaper to do copy_{to,from}_user() once than bother with
fields one by one...
