Thanks for pointing that out.
I did mean open(), which is a kernel syscall, not fopen(), which is a
libc "API".
LGPL applies for libraries, and it  deals with static linking and
dynamic linking.
For the kernel and a filesystem( JFS - GPL licensed, which is a part
of the kernel),
there is no "linking" to it, and the way we use the kernel is
different from using
(i.e. linking) a library.

IMO the approach is quite similar to LKMs so if Linus believes that LKMs are
derivative work[1], then the same conclusion should be applied to
those programs/libraries
using open().
