file-max: Yes.
inode-max: eh? (is that a 2.2-ism?)
BTW, I had a somewhat ailing, overloaded server the other day and was
getting the "VFS: file-max limit %d reached" messages. I changed the value
of /proc/sys/fs/file-max seemed to fixed it. I also donned my BOfH hat and
started killing off old/redundant user's task (hey what's life without
some fun ;)
I had a quick scan through some kernel source (grep is a wonderful thing)
kernel/sysctl.c: line 280 onwards:

[...]

and fs/file_table.c: line 61 onwards:

old_max is initalised to 0. I think its just a way of preventing multiple
KERN_INFO messages being generated.
