Hi,
According to the SuS write() can not return ENOMEM, only ENOBUFS is allowed (surprisingly read() is allowed to use both ENOMEM and ENOBUFS):
http://www.opengroup.org/onlinepubs/000095399/functions/write.html
Should we adjust sysfs write to follow the standard?

=================================================================== sysfs: write should return ENOBUFS
According to SuS ENOMEM is not a valid return code for write(), ENOBUFS should be returned.
