Subject: Re: [PATCH] x86, efi: change name of efi_no_storage_paranoia parameter to efi_storage_paranoia

Howdy Yasuaki,
  I know some boxes with small NVRAM (less than 64kb?) will meet many
  issues if we always keep ~5kb free space.
  But if we really do not keep some free space as default, many box will
  become a brick. (In fact, I just fixed a bricked dell xps 8500 last
  week. 5kb is not enough for dell xps...)
  So maybe the better way is: we check the size of nvram and decide how
  many space we retain.
