Hi,
Hello.
I have been trying to build reiser4 as a module, but the module which
is getting compiled having the "symbol" issue.
<snip>
reiser4: Unknown symbol lzo1x_1_compress
reiser4: Unknown symbol might_fault
reiser4: Unknown symbol mutex_lock_nested
reiser4: Unknown symbol zlib_deflate
reiser4: Unknown symbol writeback_inodes_wbc
</snip>
How to reproduce?
1. Download and install fedora kernel source package for latest fedora
kernel (f13)
Could you please provide a link to fedora's kernels
(I've lost my bookmarks), I'll try to take a look..
Edward.
2. Patch for reiser4
3. make the module (Warning of missing Module.symvers)
# make CONFIG_REISER4_FS=m CONFIG_REISER4_DEBUG=n M=fs/reiser4
4. Insert the module
# insmod fs/reiser4/reiser4.ko
# insmod: error inserting 'fs/reiser4/reiser4.ko': -1 Unknown symbol in module
# dmesg
reiser4: Unknown symbol lzo1x_1_compress

reiser4: Unknown symbol set_page_dirty_notag

What stuff are you using?
I am Fedora 13 x86_64
# uname -a
Linux dev06 2.6.34.7-56.fc13.x86_64 #1 SMP Wed Sep 15 03:36:55 UTC
2010 x86_64 x86_64 x86_64 GNU/Linux
Thanks,
Edward.
I could see from the reiser4 2.6.34 patch that it is adding
"EXPORT_SYMBOL" to few files in fs & mm directories of the kernel
source tree. Can we have all these symbols defined in the core source
tree of resier4 also? Do we have a patch for this already?
Thanks
Viji
