| Subject | [PATCH v2 7/9] mtip32xx: Handle FTL rebuild failure state during device initialization |
| Message-ID | <r5Wvf-7oz-9@gated-at.bofh.it> |
Allow device initialization to finish gracefully when it is in
FTL rebuild failure state. Also, recover device out of this state
after successfully secure erasing it.
