Hi Trond,
After merging the final tree, today's linux-next build (sparc
defconfig) failed like this:
`rpc_destroy_authunix' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o
Caused by commit 4c09a3aef02ef9bfab8322fadde269290563ede2 ("NFS: Ensure
the AUTH_UNIX credcache is allocated dynamically").
It also caused these warnings:
WARNING: vmlinux.o(.init.text+0x1e3b4): Section mismatch in reference from the f
unction rpcauth_init_module() to the function .exit.text:rpc_destroy_authunix()
The function __init rpcauth_init_module() references
a function __exit rpc_destroy_authunix().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __exit annotation of
rpc_destroy_authunix() so it may be used outside an exit section.
I applied the following patch for today:
From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Wed, 4 Aug 2010 14:48:54 +1000
Subject: [PATCH] nfs: remove __exit from rpc_destroy_authunix
since it is referenced from an __init function.
