bvec/iter: disallow zero-length segment bvecs zero-length bvec segments are allowed in general, but not handled by bio and down the block layer so filtered out. This inconsistency may be confusing and prevent from optimisations. As zero-length segments are useless and places that were generating them are patched, declare them not allowed.

block: add bio_for_each_bvec_all() An upcoming Btrfs fix needs to know the original size of a non-cloned bios. Rather than accessing the bvec table directly, let's add a bio_for_each_bvec_all() accessor.

docs: block: convert to ReST Rename the block documentation files to ReST, add an index for them and adjust in order to produce a nice html output via the Sphinx build system. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
