Thanks. Good reading to refresh memory. Deja-vu all over again, as they say.

But now I forget what was the last time of trouble with 64-bit readdir cookies.

Was it NFS+XFS? Or NFSv2 vs NFSv3 vs glibc with some programs stealing the extra bits?

I remember the solution was to only return 32-bit readdir cookies (31-bit, as glibc
steals one bit). This time the ext4 people are back with 64-bit cookies, only to step into
the same doo-doo...
