xfsdump manual page inaccurate for -b option?

[Jeremy Jackson <jerj@xxxxxxxxxxxx>]

Hi,

I'm reading xfsdump/common/drive_scsitape.c:calc_best_blk_and_rec_sz() 
and it seems that the manual page is inaccurate regarding the -b switch.

It indicated a 1MiB default, but reading the code, it looks like if -m 
is not used and if -b is not used, and the device is a local (not rmt) 
tape device, then the block size defaults to the lesser of the drive's 
maximum blocksize, or STAPE_MAX_RECSZ

A description of tape records (vs tape blocks) would be helpful also.

Thanks,

Jeremy
