From 8a8d56176635515d607c520580c73d61f300b409 Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Wed, 9 Nov 2016 16:47:54 +0800 Subject: [PATCH] ceph: use default file splice read callback Splice read/write implementation changed recently. When using generic_file_splice_read(), iov_iter with type == ITER_PIPE is passed to filesystem's read_iter callback. But ceph_sync_read() can't serve ITER_PIPE iov_iter correctly (ITER_PIPE iov_iter expects pages from page cache). Fixing ceph_sync_read() requires a big patch. So use default splice read callback for now.
