[LSF/MM ATTEND] all things local fs

[Eric Sandeen]

I'm interested in attending this year's summit.  I don't have a new
broad topic that hasn't already been suggested, but as someone who has
contributed at one time or another to xfs, ext2/3/4, and btrfs, I'd
like to be present to participate in the discussions.

While not an hour-long topic, I've recently played a bit with fs fuzzing
in ways that aren't typical; fsfuzzer was originally designed to test
kernelspace, but I've found it and similar approaches useful for userspace
- it's been fruitful for finding fsck and resize bugs, for example.
Might be a decent lightning topic, just for show and tell.

Another interest is in how filesystems behave in the face of ENOSPACE
(rather than queueing) from a thinly-provisioned volume which is out of
physical space; I think we may need to strive for more consistency here,
so some cross-fs discussions might be useful.

Thanks,
-Eric
