That patch removes readdirplus, and cannot therefore be responsible for
the fileid changed error that is reported in the emails below (which
does not occur when mounting with -onordirplus). It introduces a bunch
of other bugs (most which have been fixed), but not that one.
I've asked Simon for info about which NFS versions he is seeing this
with. He has not replied so far, but if you are seeing the same bug,
then I'd appreciate the same info.
Does the fileid bug occur with NFSv3 and NFSv4 or is it limited to one
or the other?
Cheers
Trond
