Message-ID: <1488922559.3877.6.camel@redhat.com> (raw)
I was doing an xfstests run on xfs with v4.11.0-rc1, and these two
warnings popped. Looks like invalidate_inode_pages2_range failed? A
small patch to print the error there showed that it was returning
-EBUSY.
Pretty easy to reproduce by running xfstests generic/095 on a KVM guest
running v4.11.0-rc1.
