xfstests: 068: run fsstress in read/write mode
PATCH 1/1 xfstests: 068: run fsstress in read/write mode
Jan Kara was testing filesystem freeze, and was consistently locking up, although my tests of 068 were passing. He pointed out that he was running in read/write mode, and it was atime updates causing the trouble. Sure enough, dropping "-w" from fsstress locked me up too. Change this so we get better (and more realistic) coverage.

Good idea.
