|  | Now that https://github.com/hanwen/go-fuse/issues/399 has
landed we can report an inode number for the root node.
Fixes https://github.com/rfjakob/gocryptfs/issues/580 | 
|  | And add a test for it.
Fixes https://github.com/rfjakob/gocryptfs/issues/724 | 
|  | Run "make format" using
go version go1.19.4 linux/amd64 | 
|  | Fixes https://github.com/golang/go/issues/54715
Output was:
$ go test ./tests/matrix -run TestConcurrentReadWrite -race
test_helpers: warning: testParentDir "/tmp/gocryptfs-test-parent-1026" does not reside on ext4, we will miss failures caused by ino reuse

  69d88505fd7f4cb0d9e4f1918de296342fe05858 go mod: declare module version v2
translated all instances of "github.com/rfjakob/gocryptfs/" to
"github.com/rfjakob/gocryptfs/v2/".
Unfortunately, this included hyperlinks.
Unbreak the hyperlinks like this:
  find . -name \*.go | xargs sed -i s%https://github.com/rfjakob/gocryptfs/v2/%https://github.com/rfjakob/gocryptfs/v2/% | 
|  |  | 
|  | 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/% | 
|  | -deterministc-names uses all-zero dirivs but does not write
them to disk anymore. | 
|  | Except xattrSupported, this is a false positive.

reported at symlink creation was the ciphertext size,
which is wrong.
