The following commit has been merged in the master branch: commit 66cd599da3c41e6b894d5b1adcceac8dbca2783d Author: Sven Eckelmann <sven.eckelmann(a)gmx.de> Date: Sat Sep 18 11:14:17 2010 +0000 batman-adv: Mark debugfs files as nonseekable We don't allow to seek in the debugfs socket and log files. Thus we should mark the file descriptor as nonseekable.
