Subject: drbd: drop wrong debugging aid
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=3e0c78d3466483ee1d6fdb4ce081e00f217db79e;p=deliverable%2Flinux.git

drbd: drop wrong debugging aid

The textual representation of resync extents in /proc/drbd presented
with proc_details >= 3 was wrong, it used bitnumbers as bitmasks.

It was not particularly useful either, and I doubt anyone has even tried
to look at it in the last few years. Drop it.
