like the following snippet: n = pwrite(fd, slab, size, off); if (n < size) { log_error("pwrite fd %d %zu bytes at offset %"PRId64" failed: %s", fd, size, off, strerror(errno)); return FC_ERROR; } when n<size ,pread or pwrite may interrupt by signal ,errno is equal to EINTR, it should process on writing,not return an error?
