Currently fstests will remove $seqres.dmesg if nothing wrong happened.
It saves some space, but sometimes it may not provide good enough
history for developers to check.
E.g. some unexpected dmesg from fs, but not serious enough to be caught
by current filter.

So instead of deleting the ordinary $seqres.dmesg, provide a new config:
KEEP_DMESG, to allow user to choose whether to keep the dmesg.

The default value for it is 0, which keeps the existing behavior by
deleting ordinary dmesg.

I changed this to a "yes"/"no" config, to match USE_KMEMLEAK, and
updated README as well.

Thanks,

Currently fstests will remove $seqres.dmesg if nothing wrong happened.
It saves some space, but sometimes it may not provide good enough
history for developers to check.
E.g. some unexpected dmesg from fs, but not serious enough to be caught
by current filter.

So instead of deleting the ordinary $seqres.dmesg, provide a new config:
KEEP_DMESG, to allow user to choose whether to keep the dmesg.

The default value for it is 0, which keeps the existing behavior by
deleting ordinary dmesg.
