This is a patchset to remove own inode hash table from nilfs.
The current version of nilfs uses inode not only to manage regular
files, directories, symlinks but also for some types of metadata and
for caching file blocks relocated by GC.
The last type of inodes is called gc-inodes, and nilfs keeps them with
an own hash table.
With this patchset, the gc-inodes will be stored in vfs inode cache
like regular inodes, and the own inode hash is deleted.
I hope this would be helpful for the vfs scalability work.
The patchset is also available from "remove-own-inode-hash" branch on:
git://git.kernel.org/pub/scm/linux/kernel/git/ryusuke/nilfs2.git
My next goal is to remove own inode allocator used to manage metadata
as files, but it still looks to need more effort.
I'd like to queue this for the next merge window if there are no
objections.
Thanks,
Ryusuke Konishi
