The following commit has been merged in the master branch: commit b6d9eb81fd3145d86ea030d1ca279b7cb25f707d Author: Linus Lüssing <linus.luessing(a)web.de> Date: Mon Oct 18 10:04:34 2010 +0000 batman-adv: Unify sysfs file names with their bat_priv atomics Both sysfs entries and variable names shall be as descriptive as possible while not exceeding a certain length. This patch renames bat_priv atomics to be equally descriptive with their according sysfs entries. Unifying sysfs and bat_priv atomic names also makes it easier to find each others pendant. The reduced ("type"-)information which was previously indicated with a _enabled for booleans got substituted by a comment in bat_priv. This patch has also been done in regards for the future BAT_ATTR_* macros (they only need one name argument instead of a file and variable name).

The following commit has been merged in the master branch: commit 3b1e5e61e4918d26ff360f90ef76513a57173105 Author: Linus Lüssing <linus.luessing(a)web.de> Date: Mon Oct 18 10:04:35 2010 +0000 batman-adv: Wrapper functions for sysfs storing Sysfs configuration options that just took a boolean value (enable(d)/disable(d)/0/1) and integer setting basically all had the same structure. To avoid even more copy and pasting in the future and to make introducing new configuration parameters for batman-adv simpler, more generic wrapper functions are being introduced with this commit. They can deal with boolean and unsigned integer parameters, storing them in the specified atomic_t variables.
