Newer kernels enable the lockdown feature when secure boot is enabled.
This feature also prevents the register mapping into userspace. Thus it

While at it, also lower the reporting level to INFO, so that one single

fabrics: print an error for ENOENT too
Many nvme commands such as discover, connect, connect-all, etc.
simply return to the prompt without printing any useful error
message when the respective nvme driver modules are not loaded in
the kernel. This is because nothing gets printed when
nvme_scan_topology() returns an ENOENT due to missing nvme system
files stemming from not loading the appropriate nvme modules.
Fix the same.
In the vtview_log structs, time_t should be used for any time_stamp
values instead of long. This ensures correct builds on 32-bit
architectures even with 64-bit time_t (e.g. armhf on Ubuntu).

util: remove unnecessary NULL check in cleanup_nvme_root()
cleanup_nvme_root() is checking whether the passed pointer is non-NULL,
but since the pointer is to a local variable, this will always be true.
Therefore, remove the check and always call nvme_free_tree().
nvme: use argconfig_parse_comma_sep_array_u16() in attach-ns
nvme_attach_ns() is using argconfig_parse_comma_sep_array()
to parse a list of ints and then copying them into a list of u16s.
Use argconfig_parse_comma_sep_array_u16() instead to save on memory
and avoid needing to copy the values to another list.
This also checks that the values fit in u16.
Also use NVME_ID_CTRL_LIST_MAX instead of hard-coding the max list size.
util: remove redundant loop condition in argconfig_parse()
Since options_count is computed as the number of options
until the first one with a NULL option field,
s->option and option_index < options_count are equivalent.
util: reduce allocation sizes in argconfig_parse()
long_opts stores up to 1 element per option, plus a help element,
and a zerored final element. So it can be allocated with length
options_count + 2 instead of options_count + 3.
short_opts stores up to 3 characters per option, plus 2 help characters,
and a NUL terminator. So it can be allocated with length
options_count * 3 + 3 instead of options_count * 3 + 5.
Also use the two arguments to calloc() instead of multiplying the sizes.
util: consolidate call paths to argconfig_parse_type()
argconfig_parse_val() already falls back on argconfig_parse_type()
if no option values match.
So always call argconfig_parse_val() from argconfig_parse()
instead of checking whether any option values are defined.
Assuming constant-length value strings, argconfig_parse_val()'s runtime
is currently quadratic in the number of option values.
For each option value, it computes a minimum prefix length
that distinguishes that option from all others.
It then checks whether the input matches up to that prefix length.
Instead, compare the input directly against each option value.
If exactly one matches, select that option value.
Otherwise, fallback on the default value parser.
util: remove empty default case in argconfig functions
Both argconfig_parse_type() and argconfig_set_opt_val()
switch on the argument value type and have an empty default case.
This is unnecessary and masks errors from unhandled enum values.
So drop the default cases.
util: use cleanup to avoid goto in argconfig_parse()
Use _cleanup_free_ in place of explicit calls to free()
in argconfig_parse(). This simplifies the code
and allows using an early return in place of a goto.
test: add test cases for argconfig comma-separated array parsing
There are no unit tests currently covering
argconfig's comma-separated integer array parsing.
Add test cases to test-argconfig-parse.c

readable option which prints additional useful info. So fix the
-v option to make it synonymous with the -H option here. And while
we are at it, move the latency info from current INFO level (i.e.
-v logging) to DEBUG level (i.e. -vv logging) since it is better
suited there.
