Package: libsys-statistics-linux-perl Version: 0.66-3 Summary: The new linux kernel provides two additional columns in /proc/diskstats and thus the perl module DiskStats.pm has to be updated to parse/match the two additional columns.
Details: Perl comes with the utility module /usr/share/perl5/Sys/Statistics/Linux/DiskStats.pm In line 246 the module reads the file /proc/diskstats and tries to parse it with different regular expressions. The first try is done with: if ($line =~ /^\s+(\d+)\s+(\d+)\s+(\S+)\s+(\d+)\s+\d+\s+(\d+)\s+\d+\s+(\d+)\s+\d+\s+(\d+)\s+\d+\s+\d+\s+\d+\s+\d+(?:(?:\s+\d+){4})?$/) { The new format of /proc/diskstats contains two additional columns and thus fails to parse the information. With Debian bullseye the diskstats line looks e.g. like the following example: 11 0 sr0 15 0 0 1 0 0 0 0 0 20 1 0 0 0 0 0 0 Thus the regex fails to match. The added columns are documented at: https://www.kernel.org/doc/Documentation/ABI/testing/procfs-diskstats If the additional params are not relevant, the regex can be changed to e.g. if ($line =~ /^\s+(\d+)\s+(\d+)\s+(\S+)\s+(\d+)\s+\d+\s+(\d+)\s+\d+\s+(\d+)\s+\d+\s+(\d+)\s+\d+\s+\d+\s+\d+\s+\d+(?:(?:\s+\d+){4,6})?$/) { Would be nice if someone of the maintainers can take a closer look at that issue.
