[PATCH v4 6/8] block: bio: remove BIO_MAX_SECTORS

From: Ming Lei
Date: Thu Apr 14 2016 - 07:49:32 EST


No one need this macro, so remove it. The motivation is
for supporting multipage bvecs, in which we only know
what the max count of bvecs is supported in the bio,
instead of max size or max sectors.
