Ivan Vecera f1db1b8055 kernfs: fix regression in kernfs_fop_write caused by wrong type ... commit ba87977a49913129962af8ac35b0e13e0fa4382d upstream. Commit b7ce40cff0 ("kernfs: cache atomic_write_len in kernfs_open_file") changes type of local variable 'len' from ssize_t to size_t. This change caused that the *ppos value is updated also when the previous write callback failed. Mentioned snippet: ... len = ops->write(...); <- return value can be negative ... if (len > 0) <- true here in this case *ppos += len; ...
