[PATCH 0/7] nvme: cleanup ida_simple_[get|remove]

[Sagi Grimberg]

We have the simpler and more convenient idr_[alloc|free], use them
instead.

[PATCH 1/7] nvme-tcp: fix bogus request completion when failing to send AER

[Sagi Grimberg]

AER is not backed by a real request, hence we should not incorrectly
assume that when failing to send a nvme command, it is a normal request
but rather check if this is an aer and if so complete the aer (similar
to the normal completion path).

[PATCH 2/7] nvme: replace ida_simple[get|remove] with the simler ida_[alloc|free]

[Sagi Grimberg]

ida_simple_[get|remove] are wrappers anyways.

Also, use ida_alloc_min with the ns_ida as namespace
enumeration starts with 1.

     but rather check if this is an aer and if so complete the aer (similar
     to the normal completion path).

So which of the two versions should we go with?  Either one will need
reviews :)

With the exception of 1/7 that sneaked in Sagi's set, the patches are
identical (including the file ordering despite no dependency!), and both
