Hi,
I'd like to attend the LSF/MM conference this year.
I think I can contribute to a few areas that are being discussed this year:
- how to provide better information for the filesystem to optimize allocation.
- power/failure tests
- performance aspects, etc.
Besides that, I'd like to talk about the following,
- combining overlayfs with btrfs to properly fix overlayfs copy-up slowness.
- fragmentation control in Copy-On-Write filesystems. (setting a reasonable
large allocation unit and performing RMW, etc?)
Since xfs is also going to have reflink, so xfs is also regarded as COW
FS, having some generic ideas for this topic would help a lot.
- mount individual subvolumes (in btrfs) with different selinux label, this
will be useful in container senarios when btrfs being their storage driver.
(I've finished the patch for the above selinux label support, but it can ends up
with inode leak if it's not used in the container way, which is assuming the
top subvolume is always being the last one to unmout.)
thanks,
-liubo
