This call can fail if there are dirty pages. The preceding call to filemap_write_and_wait_range() will normally remove dirty pages, but as inode_lock() is not held over calls to ceph_direct_read_write(), it could race with non-direct writes and pages could be dirtied immediately after filemap_write_and_wait_range() returns If there are dirty pages, they will be removed by the subsequent call to truncate_inode_pages_range(), so having them here is not a problem. If the 'ret' value is left holding an error, then in the async IO case (aio_req is not NULL) the loop that would normally call ceph_osdc_start_request() will see the error in 'ret' and abort all requests. This doesn't seem like correct behaviour. So use separate 'ret2' instead of overloading 'ret'.
