Commit Message

Guixin Liu Oct. 14, 2024, 9:01 a.m. UTC 
Add an optional argument --resv_enable to _nvmet_target_setup() and
propagate it to _create_nvmet_subsystem() and _create_nvmet_ns().

One can call functions with --resv_enable to enable reservation
feature on a specific namespace.

And also make _create_nvmet_ns and _create_nvmet_subsystem to parse
for arguments, this makes these functions more flexible to use.
