In case ANM event occurs on open band there
can be situation that reloc will try to read
block on which there is ongoing write.
This is happening because lba valid map is
updated before write submission to allow sent
consistent metadata to disk before all user
writes are completed.
Added write offset to the each chunk and
add check to reloc if particular ppa is written
on that chunk.

Direct wptr allows for writing to band with externally
provided PPA, rather than one assigned by the wptr. This
can be useful when padding open bands during recovery or
bdev creation, as ftl can find partially written end meta
with no way to close the band with valid data, that would
conform to an already written CRC value.
This does mean that I/O sender is responsible for calculating

For the latest TLC NAND, one write buffer unit (rwb batch)
needs to be spread over three PUs instead of being allocated
to a single PU for better sequential read performance
since the optimal write size(ws_opt) of 3D TLC NAND is
3 times bigger than the optimal read size(rs_opt).
I added num_interleave_units in 'struct spdk_ftl_conf'
to configure the number of interleaving units per ws_opt.
If num_interleave_units is set as 1, the whole of the ws_opt
blocks are placed sequentially around each PU.
If num_interleave_units is set as N, the 1/N of the ws_opt
blocks are staggered. So consecutively numbered blocks
are separated by ws_opt / num_interleave_units.
The sequential read performance is improved from 1.9GiB/s
up to 2.97GiB/S with this patch on our system. No performance
degradation is observed on sequential writes or
4KB random reads/writes.
Please refer to the Trello card for more details.

Added check before write submission to indicate if
LBA was update in meantime. In such case don't set band's
metadata and rwb entry cache bit. Previous implementation
invalidates such address during write completion and could
cause that inconsistent lba map was stored into disk.

The patch adds support for retrieving asynchronous media management
events sent by the drives. SSDs needs to inform the host of various
incidents concerning the data placed on the media. The events include
wear-leveling, read disturb, and background data refresh.
In order to poll for this asynchronous events, a separate thread is
added that polls for completion of admin commands for each of Open
Channel disk and dispatches the ANM events to the appropriate block
devices.
