URL: https://svnweb.freebsd.org/changeset/base/347892
Log:
LinuxKPI: Finalize import of seq_file.
seq_file.h and linux_seq_file.c was imported form ports earlier but
linux_seq_file.c was never compiled in with the module. With this
commit base seq_file will replace ports seq_file and it required a
few modifications to not break functionality and build.
