Hi Jens,

Can we get this in ?

Hi Jens,

Recently we've added several new operations for zoned block devices
blk-zone.c (ZBD). These operations have a direct effect on the
zone-state machine present in the null_blk_zoned.c.

This will allow us to add new testcases in blktests in order to verify
the correct operations on the driver side.

This is a small patch series which adds tracepoints for the null_blk
block driver when configured in a zoned mode (with command line
parameter zoned=1).

The first patch is a prep patch that adds a helper to stringify zone
conditions which we use in the trace, the second patch adds new
tracepoint definitions and the third patch allows null_blk_zoned to
trace operations.

Please have a look at the end for sample test output which has tests
for CONFIG_BLK_DEV_ZONED and !CONFIG_BLK_DEV_ZONED.

Regards,
Chaitanya
