Bug 437278 – net-fs/openafs-kernel-1.6.1-r1 with gentoo-sources:3.6 - .../work/openafs-1.6.1/src/libafs/MODLOAD-3.6.0-gentoo-MP/afs_bypasscache.c:450:4: error: ‘KM_USER0’ undeclared (first use in this function)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Oliver Freyermuth 2012-10-05 10:20:41 UTC]

Compilation fails after upgrading to gentoo-sources 3.6.0. 



Reproducible: Always

Steps to Reproduce:
1. Upgrade to gentoo-sources 3.6, configure and build
2. Recompile openafs-kernel-1.6.1-r1
Actual Results:  
Compilation fails

Expected Results:  
Compilation works

This problem has already been fixed upstream. 
Patches can be fetched from upstream's git, I have tested the .patch-files prepared here (applicable against openafs-kernel 1.6.1-r1): 
http://cvs.rpmfusion.org/viewvc/rpms/openafs-kmod/devel/?root=free
(Numbers 0001 - 0008)
by dropping them into the patches-directory and enabling epatch_user. 
Compilation is fine with those patches applied, and OpenAFS works again with linux 3.6.

Output of emerge --info '=net-fs/openafs-kernel-1.6.1-r1'

Output was generated after installation of the 'fixed' version with epatch_user, but otherwise unchanged config

I have implemented this on 2 systems, one with 3.4.9 and one with 3.6.1.  On both systems it compiles and the module loads just fine.  I've done minimal testing on both systems so far - directory (ls -l) listing and a little file reading/writing.  Heavier usage will have to wait for the opportunity.  (Basically working from home, without the employer-provided Linux laptop)

[Comment 4 Bernd Feige 2012-10-16 13:57:36 UTC]

Patches apply, compile and work well here with the current 3.6 kernel (AFS clients).

[Comment 5 Dale Pontius 2012-10-18 14:41:33 UTC]

I have found one minor oddity, and I'm not sure where it's from.  Once I compiled the new kernel module, I had to manually run "depmod -a" before I could actually start afs.  Not a biggie, but I haven't had to do that manual step in ages.

should be all set now in the tree; thanks for the report!
