For 4K disks 'endofpart' is an index of the last 4K sector used by partition. mdadm is using number of 512-byte sectors, so value returned by get_last_partition_end must be multiplied by 8 for devices with 4K sectors. Also, unused 'ret' variable has been removed. Signed-off-by: Mariusz Dabrowski <redacted> --- util.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-)
I am a little wary of this since I don't have any 4k sector drivers to
test with, so I will come yelling at you if this breaks something :)

I really would prefer to see a parenthesis around this here and use of
proper spacing.
Thanks,
