Andriy Gapon 8a3883cfb7 zfs vn_has_cached_data: take into account v_object->cache != NULL ... This mirrors code in tmpfs. This changge shouldn't affect much read path, it may cause unnecessary vm_page_lookup calls in the case where v_object has no active or inactive pages but has some cache pages. I believe this situation to be non-essential. In write path this change should allow us to properly detect the above case and free a cache page when we write to a range that corresponds to it. If this situation is undetected then we could have a discrepancy between data in page cache and in ARC or on disk. This change allows us to re-enable vn_has_cached_data() check in zfs_write. NOTE: strictly speaking resident_page_count and cache fields of v_object should be exmined under VM_OBJECT_LOCK, but for this particular usage we may get away with it.
