Subject: tools/testing/nvdimm: improve emulation of smart injection
Git-commit: b4d4702f30e09ed1311e560334eb25fc2015c8ce
Patch-mainline: v4.19-rc1
References: FATE#326060
The emulation for smart injection commands for nfit neglected to check
the smart field validity flags before injecting to that field. This is
required as a way to distinguish un-injection vs. leave-alone.
The emulation was also missing support for un-injection entirely. To add
this support, first, fix the above flags check. Second, use the
'enable' field in the injection command to determine injection vs
un-injection. Third, move the smart initialization struct to be a global
static structure for the nfit_test module. Reference this to get the
smart 'defaults' when un-injecting a smart field.
