[PATCH 0/4] nvmet: admin-cmd related cleanups and a fix

[Chaitanya Kulkarni]

Hi,

There are three functions where local variable ns is used instead of
using req->ns which leads to duplicate nvmet_put_namespace() calls.
We can just use req->ns and not the local variable to avoid duplicate
calls. First three patches fix that.

The last patch sets the right error status code when namespace is not
found in nvmet_execute_identify_ns().

I've tested this series with nvme blktests, all the testcases are
passing.

-ck

Chaitanya Kulkarni (4):
  nvmet: remove extra variable in smart log nsid
  nvmet: remove extra variable in identify ns
  nvmet: remove extra variable in id-desclist
  nvmet: set right status on error in id-ns handler
