Cover letter [RFC][PATCH 00/11] track files for checkpointability

This takes a suggestion of Ingo's along with comments from lots of other people. It can track whether a given file is able to be checkpointed. It introduces a f_op to allow easy customization like the reset of the VFS.

You can also find these patches in git:

http://git.kernel.org/gitweb.cgi?p=linux/kernel/git/daveh/linux-2.6-cr.git;a=shortlog;h=dave-v13.4

Sorry if anybody got this twice. I'm fighting with git-send-email.
