    [ https://issues.asterisk.org/jira/browse/DAHLIN-390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=255469#comment-255469 ] 

Shaun Ruffell commented on DAHLIN-390:
--------------------------------------

That is for another issue fixed on the branch. The specific fix for that issue is https://git.asterisk.org/gitweb/?p=dahdi/linux.git;a=commit;h=d228a12f1caabdbcf15a757a0999e7da57ba374d

If you can, you probably want to checkout the current tip of the next branch and build that:

{code}
$ git clone git://git.asterisk.org/dahdi/linux.git -b next dahdi-linux
$ cd dahdi-linux
$ make
{code}

> Many functions that deal with the /proc filesystem had their prototypes changed; now they use a differently named structure, with differently named fields, which apperently does the same thing but does nor require a "owner" field.
