[LTP] [PATCH] ltp_block_dev: Check HAVE_LINUX_GENHD_H to include genhd.h

[Petr Vorel]

Hi Tiezhu,

> After the LTP commit d4dd360b05f8 ("device-drivers/acpi/ltp_acpi_cmds:
> Fix build errors"), HAVE_LINUX_GENHD_H is defined to 1 if you have the
> <linux/genhd.h> header file.

> The macro definition DISK_NAME_LEN may be completely removed, so it is
> better to use #ifdef HAVE_LINUX_GENHD_H to include genhd.h.

Indeed, at least 4.12 based kernel does not need it.
In that case please send a new patch. Thanks!

Kind regards,
