[v2,0/3] zonefs: introduce -o explicit-open mount option

Message

Johannes Thumshirn Sept. 9, 2020, 10:26 a.m. UTC

Introduce a mount option for explicitly opening a device's zones when opening
the seq zone file for writing. This way we prevent resource exhaustion on
devices that export a maximum open zones limit. 

Johannes Thumshirn (3):
  zonefs: introduce helper for zone management
  zonefs: open/close zone on file open/close
  zonefs: document the explicit-open mount option
