Subject: [PATCH synaptics] eventcomm: if we get a read error other than
|
|
|
553148 |
EAGAIN, remove the fd
|
|
|
553148 |
|
|
|
553148 |
Otherwise poll() keeps on triggering on our fd until udev gets around to
|
|
|
553148 |
notifying the server that the device is in some state of deadness. Meanwhile,
|
|
|
553148 |
the input thread is busy filling the log up with "Read error" messages. Great
|
|
|
553148 |
way to test file systems and their capacity to handle out of space scenarios
|
|
|
553148 |
but otherwise a bit pointless. Those FS developers should write their own
|
|
|
553148 |
tests instead of relying on the synaptics driver!
