ignore ENOTSUPP (524) for fiemap error #644
Description
In mfu_flist_copy.c:mfu_copy_file_fiemap()
if (ioctl(mfu_src_file->fd, FS_IOC_FIEMAP, fiemap) < 0) {
if (errno == ENOTSUP) {
/* silently ignore */
} else {
MFU_LOG(MFU_LOG_ERR, "fiemap ioctl() failed for src '%s' (errno=%d %s)",
src, errno, strerror(errno));
}
goto fail_fiemap;
}When errno is ENOTSUP (95) the error message is skipped, but otherwise the behavior is the same. However lustre often returns ENOTSUPP (524) as mentioned in #545. I think that (errno == 524) should be silently ignored as well.
