Subject: [PATCH] null_blk: Add zone_nr_conv to features
Git-commit: 6d09c4086ed9fc72afb3be4b47ecfa34f57f15f9
Patch-Mainline: v5.5-rc1
References: bsc#1175995,jsc#SLE-15608
For a null_blk device with zoned mode enabled, the number of
conventional zones can be configured through configfs with the
zone_nr_conv parameter. Add this missing parameter in the features
string.
