Hi,
I recently came across this when I was looking for various ways to convert GFID to Path[1].
I have tested "build-pgfid" option for basic sanity. It's documented in the commit msg of change[2]. Found one small issue[3]. There could be others.
Users should be aware that these xattrs generated only for newly created dirs/files and are not built for already existing dirs/files.

Didn't see this documented, but the log message in posix.c says: "update-link-count-parent is enabled. Thus for each file an extended attribute representing the number of hardlinks for that file within the same parent directory is set." Why would this be necessary?

sure for ancestry paths and gfid to path conversion - AFAIK
# gluster volume set <volname> build-pgfid on
Enables this feature. Never tested it personally.
