Subject: [RFC v4] nvfs: a filesystem for persistent memory

Hi

I announce a new version of NVFS - a filesystem for persistent memory.
You can download it at:
	http://people.redhat.com/~mpatocka/nvfs/
	git://leontynka.twibright.com/nvfs.git
Description of the filesystem layout:
	http://people.redhat.com/~mpatocka/nvfs/INTERNALS


Changes since the last release:

* updated for the kernels 5.13 and 5.14-rc

* add the ability to export the NVFS filesystem over NFS:
	- each directory contains a pointer to its parent directory 
	- add the 'generation' field to inodes
	- the ability to open files by inode numbers

* fixed some endianity conversions

* fixed some sparse warnings

* fixed a bug in extended attributes
