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>

|
The Kyber I/O scheduler is a low-overhead scheduler suitable for
|
|
multiqueue and other fast devices. Given target latencies for reads and
|
|
synchronous writes, it will self-tune queue depths to achieve that
|
|
goal.

BFQ I/O scheduler for BLK-MQ. BFQ distributes the bandwidth of
|
|
of the device among all processes according to their weights,
|

regardless of the device parameters and with any workload. It

real-time applications. Details in
