Hi,
following the discussions on the I-pipe patch, here is a proposed
modification for the posix thread signals relying on
xnshadow_call_mayday. xnshadow_call_mayday is modified to not send a
signal, expecting its caller to have sent one, then a pending signal to
a user-space posix skin thread causes xnshadow_call_mayday to be called.
Whereas it works, what still seems strange with this implementation is
to have to set the XNAMOK bit to cause xnshadow_sys_mayday to switch to
secondary mode.
Thanks in advance for your review.
Regards.
