v3:
patch 2:
- Don't export ndctl_namespace_get_injection_bounds (Dan).
v2:
patch 1:
- use poll() instead of a sleep loop when waiting for a scrub. (Dan)
patch 2 (new):
- move the acpi nfit specific routines into generic wrappers exported
by the library. (Dan)
patch 3:
- rename 'clear' to 'uninject' use 'block' instead of
'sector' (Dan)
- cleanup the manpage to remove ACPI/NFIT references.
patch 4:
- Add the actual inject-error unit test instead of just test
boilerplate
These patches add a new command to ndctl for error injection. They are
implemented such that the interface provided to a user is consistent
with the kernel - i.e. all media errors are expected/displayed in terms
of 512 byte sectors. The underlying ACPI DSMs need and provide byte
relative offsets/lengths, but these are converted to 512B sectors for
consistency.
These also update unit tests to use the new error injection commands,
and add two new unit tests - first, to test the error injection commands
themselves, and second, to test BTT error clearing.
Vishal Verma (6):
libndctl: add APIs to get scrub count and to wait for a scrub
libndctl: add error injection related interfaces
ndctl: add an inject-error command
ndctl/test: add a new unit test for inject-error
ndctl/test: update existing unit tests to use inject-error
ndctl/test: add a new unit test for BTT error clearing
