[stgt] [PATCH 1/1] tgtd: allow 'immutable' files and have them become read-only LUNs.

[ronnie sahlberg]

Agree that it is suboptimal, but changing the signature would have
been more intrusive.

Do you want to to re-do the patch differently to pass flags to the
function instead.

Or optionally, the same functionality could be provided instead
through a new    bs_rdonly.c  backend.
Do you want to to implement a replacement patch?


regards
