[asterisk-bugs] [JIRA] (DAHLIN-390) DAHDI does not compile on kernels >= 5.6

[Juan Carlos Castro y Castro (JIRA)]

    [ https://issues.asterisk.org/jira/browse/DAHLIN-390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=255527#comment-255527 ] 

Juan Carlos Castro y Castro commented on DAHLIN-390:
----------------------------------------------------

Thank you. Rather than applying these to the release tarball, I'm now just using the next branch.

These two are kind of showstoppers, don't you think? They should appear more quickly in the releases, IMHO.

Thanks for the help!

> 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.
