Message

Lets start from fs/select.c

I have no idead how to test these changes, please review.

On top of "[PATCH -mm V2 1/1] signal: simplify set_user_sigmask/restore_user_sigmask"

it seems that we can do more unrelated cleanups in this code, say,
poll_select_prepare(enum poll_time_type pt_type).

Oleg.
