ceph: don't use truncate_pagecache() to invalidate read cache truncate_pagecache() drops dirty pages, it's dangerous to use it to invalidate read cache. Besides, we shouldn't start invalidating read cache while there are buffer writers. Because buffer writers may add dirty pages later. Signed-off-by: Yan, Zheng <zyan@redhat.com>
