Author: bz Date: Sun Dec 13 16:53:06 2009 New Revision: 200479 URL: http://svn.freebsd.org/changeset/base/200479 Log: MFC r197518: lindev(4) [1] is supposed to be a collection of linux-specific pseudo devices that we also support, just not by default (thus only LINT or module builds by default). While currently there is only "/dev/full" [2], we are planning to see more in the future. We may decide to change the module/dependency logic in the future should the list grow too long. This is not part of linux.ko as also non-linux binaries like kFreeBSD userland or ports can make use of this as well.
