Subject: [PATCH 0/3] floppy: suppress UBSAN warning in setup_rw_floppy()
Date: Tue, 21 Apr 2020 15:57:19 +0300	[thread overview]
Message-ID: <20200421125722.58959-1-efremov@linux.com> (raw)

These patches are based on Willy's cleanup patches
https://lkml.org/lkml/2020/3/31/609.

The first two patches indroduce defines to make it more clear why
cmd_count in struct floppy_raw_cmd allows cross-boundary access for
cmd, reply_count, reply fields. The last one handles the warning.

Denis Efremov (3):
  floppy: add FD_AUTODETECT_SIZE define for struct floppy_drive_params
  floppy: add defines for sizes of cmd & reply buffers of floppy_raw_cmd
  floppy: suppress UBSAN warning in setup_rw_floppy()
