offset from which to truncate
Overview
Called under (and serialised by) inode->i_mutex.
Note
When this function returns, there can be a page in the process of deletion (inside __delete_from_page_cache) in the specified range. Thus mapping->nrpages can be non-zero when this function returns even after truncation of the whole mapping.
