The return value is zero for success, else a negative errno. It should
be checked, since the get/set calls don't have error returns and since
misconfiguration is possible. (These calls could sleep.)
+For output GPIOs, the value provided becomes the initial output value.
+This helps avoid signal glitching during system startup.
+
Setting the direction can fail if the GPIO number is invalid, or when
that particular GPIO can't be used in that mode. It's generally a bad
idea to rely on boot firmware to have set the direction correctly, since

Fix hang (in i_size_read) when simultaneous size update of same remote file

+When DOS attribute of file on non-Unix server's file changes on the server side
