Forward the backing filesystem's STATX_BTIME on Linux while preserving
existing metadata translations and fallback behavior.
On Linux 6.6 and newer, this allows statx consumers such as GNU stat
to report birth time when the backing filesystem provides it. Older
kernels and backing filesystems without birth-time support retain the
existing behavior. No on-disk format change or migration is required.
Reverse mode remains unchanged.
Fixes #868.

The new api guarantees that the value is aligned, preventing
stuff like this on 32 bit platforms:

Our git version is v2+ for some time now, but go.mod
still declared v1. Hopefully making both match makes
https://pkg.go.dev/github.com/rfjakob/gocryptfs/v2 work.
All the import paths have been fixed like this:
find . -name \*.go | xargs sed -i s%github.com/rfjakob/gocryptfs/%github.com/rfjakob/gocryptfs/v2/%

Use the Gen field (inode generation) to distinguish hard links
while passing the real inode numbers to userspace.

fusefrontend: implement recursive diriv caching2021-06-25T11:56:53+00:00Jakob Unterwurzacher2021-06-25T09:33:18+00:00urn:sha1:84e702126ac4f017e12150532bfaed675dee2927
The new contrib/maxlen.bash showed that we have exponential
runtime with respect to directory depth.
The new recursive diriv caching is a lot smarter as it caches
intermediate lookups. maxlen.bash now completes in a few seconds.
