c6dbe0ab0e lib/ftl: Keep tracing functions under define flag
Tracing functions introduce performance overhead
so by default keep them only in debug builds.

336505abbf lib/ftl: use per-io_channel write buffers
Replaced single global write buffer with the per-io_channel write
buffers.  This means that the "rwb" module and all of its references
were removed and replaced with the recently added interfaces.

e47e16d3a4 lib/ftl: Replace ftl_ppa struct with ftl_addr
FTL working on top of zoned bdev doesn't need
physical page address (PPA) anymore.
ftl_ppa was replaced with ftl_addr which represents
zoned device addressing schema.

9ed090d23d lib/ftl: traces refactor
Replaced tpoint_ids generated based on the properties of the IO with a
static list of tpoint_ids, to fit inside the per-group maximum tpoint
limit (64).

8331ebd19c ftl: Added trace support
This patch adds supplementary tracing for OCSSD library to allow
for more efficient debugging and profiling of the user I/O path
as well as the background tasks (maintaining write pointer,
defragmentation, ANM event handling, etc.).

5c3591c72e ftl: Added initialization module
This patch adds OCSSD device initialization consisting of the
following:
 * retrieving SSD's geometry and its state
 * verifying configuration
 * initializing core structures (L2P, bands, write buffer, write
 pointers, bad block tables, etc)
 * initializing threads

e9a236d275 ftl: Initial headers
This patch introduces core structures required for implementing FTL on
top of Open Channel drives. The Open Channel specification describes raw
access to the media on the SSD. The FTL consumes that API and exposes a
block device interface.

The implementation is based on the revision 2.0 of the Open Channel SSD
specification.
