Subject: bug#72770: stat: filesystem ID regression in 9.5 with musl libc
Date: Fri, 23 Aug 2024 09:14:34 +0200

With coreutils 9.5 stat -f -c %i returns wrong value with musl libc.

$ docker run --rm -it -v /tmp:/tmp alpine:3.20 sh -c "apk add --quiet coreutils && stat --version && stat -f -c %i /tmp && busybox stat -f -c %i /tmp"
stat (GNU coreutils) 9.5

Coreutils returns 4dc59e8900000000 instead of the expected 4dc59e89680d9b7c.

With 9.4 this works as expected:

$ docker run --rm -it -v /tmp:/tmp alpine:3.19 sh -c "apk add --quiet coreutils && stat --version && stat -f -c %i /tmp && busybox stat -f -c %i /tmp"
stat (GNU coreutils) 9.4
