| Subject: efi: Expose non-blocking set_variable() wrapper to efivars |
| |
| From: Ard Biesheuvel <ard.biesheuvel@linaro.org> |
| |
| commit 9c6672ac9c91f7eb1ec436be1442b8c26d098e55 upstream. |
| |
| Commit 6d80dba1c9fe ("efi: Provide a non-blocking SetVariable() |
| operation") implemented a non-blocking alternative for the UEFI |
| SetVariable() invocation performed by efivars, since it may |
| occur in atomic context. However, this version of the function |
| was never exposed via the efivars struct, so the non-blocking |
| versions was not actually callable. Fix that. |
