[Peter Viskup <skupko.sk@gmail.com>]

Package: linux-latest
Version: 4.9.110-3+deb9u4
Severity: important

After kernel update on Debian9 system from 4.9.65-3+deb9u1 to
4.9.110-3+deb9u4 the fcheck cron job run +45000 seconds instead of
original +8500 seconds (tested twice with same results).

Tested with command
$ perf stat -B -o fcheck.perf.stat nocache nice ionice -c3
/usr/sbin/fcheck -asxrf /etc/fcheck/fcheck.cfg >/var/run/fcheck.out
2>&1

$ grep "time elapsed" fcheck.perf.stat*
fcheck.perf.stat:    8573.851887243 seconds time elapsed
fcheck.perf.stat2:    8544.105864343 seconds time elapsed
fcheck.perf.stat3:   45450.729247342 seconds time elapsed
