Hello all,
I'm building an off-tree kernel-dependent package (iscsitarget),
which results a set of kernel modules. This is a cross-platform build,
with a toolchain installed on an old RH7.3 host (host GCC v2.96)
Unfortunately, build fails with the following error:
->

The origin of the error is obvious - C99 declaration in match().
The patch is trivial:

Subject: [PATCH] Removed C99 declaration, which breaks build of modpost with
old compilers.

Could someone please comment on the patch and apply?
Also, what is a clean way to clean up a 'scripts' directory only?
Is this ever possible?
Thanks in advance,
Sergei
