Subject: [PATCH 2.6] input: do not suppress 0 value relative events
Date: Sat, 4 Oct 2003 02:22:57 -0500 [thread overview]
Message-ID: <200310040223.01664.dtor_core@ameritech.net> (raw)
Input: input susbsystem should not drop 0 value relative events,
otherwise unsuspecting programs will loose transitions from
non-zero to 0 deltas. We should not require userland authors
to consult with kernel implementation details all the time,
but follow the principle of least surprise and report
everything.
