Description Daniel Choong 2004-03-17 16:48:30 UTC

I recently emerged linux-2.4.22-gentoo-r7.
I compiled ntfs as a modules. At the end of make modules_install where it runs depmod -ae ....,
I get an unresolved symbols message with ntfs.o , the function was __mark_dirty

Reproducible: Always
Steps to Reproduce:
1. compile ntfs as a module, include debug and write functions
2. at the end of make modules_install you will see it
3. or just run depmod -a

Actual Results:  
Unresolved symbols with ntfs.o . I cannot reproduce the bug now because I think
I've found out what was missing.

Expected Results:  
nothing.

I saw from the following patch that

EXPORT_SYMBOL(__mark_dirty);

was missing from kernel/ksyms.c
I put it in and now it works.

At first I tried putting in

EXPORT_SYMBOL(end_buffer_io_sync);

but I got errors with that. I think it was exported somewhere else.
