Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

SUNRPC/NFS: Add Kbuild dependencies for NFS_DEBUG/RPC_DEBUG This allows us to turn on/off the dprintk() debugging interfaces for those distributions that don't ship the 'rpcdebug' utility. It also allows us to add Kbuild dependencies. Specifically, we already know that dprintk() in general relies on CONFIG_SYSCTL. Now it turns out that the NFS dprintks depend on CONFIG_CRC32 after we added support for the filehandle hash.

SUNRPC: Use RCU to dereference the rpc_clnt.cl_xprt field A migration event will replace the rpc_xprt used by an rpc_clnt. To ensure this can be done safely, all references to cl_xprt must now use a form of rcu_dereference().

SUNRPC: Use KERN_DEFAULT for debugging printk's Our dprintk() debugging facility doesn't specify any verbosity level for it's printk() calls, but it should. The default verbosity for printk's is KERN_DEFAULT. You might argue that these are debugging printk's and thus the verbosity should be KERN_DEBUG. That would mean that to see NFS and SUNRPC debugging output an admin would also have to boost the syslog verbosity, which would be insufferably noisy.
