Fix assumptions about name spaces in NVME driver. First, it assumes cdata.nn is the number of configured devices. However, it is the number of supported name spaces. Second, it assumes that there will never be more than 16 name spaces supported, but a certain drive I'm testing reports 1024. It assumes that name spaces are a tightly packed namespace, but the standard seems to indicate otherwise. Finally, it assumes that an error would be generated when quearying an unconfigured namespace. Instead, it succeeds but the identify data is all zeros. Fix these by limiting the number of name spaces we probe to 16. Remove aborting when we find one in error. When the size of the name space is zero, ignore it. This is admittedly a bandaide. The long term fix will be to participate in the enumeration and name space change protocols definfed in the NVNe standard. Sponsored by: Netflix

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
