Subject: Re: [PATCH V8 6/7] sd_zbc: Initialize device request queue zoned data
Date: Mon, 20 Nov 2017 21:36:55 -0500	[thread overview]
Message-ID: <yq1a7zgnyrc.fsf@oracle.com> (raw)
In-Reply-To: <20171109065707.17210-7-damien.lemoal@wdc.com> (Damien Le Moal's message of "Thu, 9 Nov 2017 15:57:06 +0900")


Damien,

> Initialize the seq_zones_bitmap, seq_zones_wlock and nr_zones fields
> of the disk request queue on disk revalidate. As the seq_zones_bitmap
> and seq_zones_wlock allocations are identical, introduce the helper
> sd_zbc_alloc_zone_bitmap(). Using this helper, reallocate the bitmaps
> whenever the disk capacity (number of zones) changes.
