Hi,

cvs can't provide you with that kind of information, because it doesn't
remember it (cvs works on file-by-file base). But, it can tell you when
the 1.337 commit to vfs_syscalls.c happened. 

$ cvs log -r1.337 vfs_syscalls.c
...
revision 1.337
date: 2004/02/14 18:31:11;  author: rwatson;  state: Exp;  lines: +8 -0
...

You can then use the archive of the cvs-src mailing list at
http://lists.freebsd.org/pipermail/cvs-src/2004-February to find the
commit:

http://lists.freebsd.org/pipermail/cvs-src/2004-February/018554.html

That should tell you all modified files in this commit.

HTH,
Andreas

PS: The log information for a single file can also be found via
    http://cvsweb.freebsd.org
