[PATCH v3 0/3] block: add zone write granularity limit

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The first patch in this series introduces the zone write granularity
queue limit to indicate the alignment constraint for write operations
into sequential zones of zoned block devices.

The second patch fixes adds the missing documentation for
zone_append_max_bytes to the sysfs block documentation.

The third patch switch zonefs to use this new limit as the file block
size instead of using the physical block size.

Changes from v2:
* Added patch 3 for zonefs
* Addressed Christoph's comments on patch 1 and added the limit
  initialization for zoned nullblk

Changes from v1:
* Fixed typo in patch 2

Damien Le Moal (3):
  block: introduce zone_write_granularity limit
  block: document zone_append_max_bytes attribute
  zonefs: use zone write granularity as block size
