This could not land with the base miscdevice abstractions due to the dependency on File. The last two patches enable you to use the `dev_*` macros to print messages in miscdevice drivers. Signed-off-by: Alice Ryhl <aliceryhl@google.com> --- Changes in v3: - Fix build error in fops->open() patch. - Improve wording of some comments in fops->open() patch. - Update commit message with more info on why `struct miscdevice` is only made available in fops->open() and not other hooks. - Include Lee's device accessor patch, since it's a needed component to use the `dev_*` printing macros with miscdevice. - Link to v2: https://lore.kernel.org/r/20241209-miscdevice-file-param-v2-0-83ece27e9ff6@google.com Changes in v2: - Access the `struct miscdevice` from fops->open(). - Link to v1: https://lore.kernel.org/r/20241203-miscdevice-file-param-v1-1-1d6622978480@google.com --- Alice Ryhl (2): rust: miscdevice: access file in fops rust: miscdevice: access the `struct miscdevice` from fops->open() Lee Jones (1): rust: miscdevice: Provide accessor to pull out miscdevice::this_device rust/kernel/miscdevice.rs | 66 +++++++++++++++++++++++++++++++++++++++-------- 1 file changed, 55 insertions(+), 11 deletions(-) --- base-commit: fac04efc5c793dccbd07e2d59af9f90b7fc0dca4 change-id: 20241203-miscdevice-file-param-5df7f75861da Best regards,
