Description
Description / Steps to reproduce the issue
Flash partition configured as BCH layer (device driver created with bchdev_register
) doesn't allow stat
call to obtain the information about an underlying MTD device/flash. This is caused by INODE_IS_MTD
not being set and thus
function inode_stat
falls to the last else
statement and does not fill the necessary information.
This is a logical output as BCH layer is registered as a standard character device driver, therefore it is not considered as MTD but as a standard driver (ADC, PWM, etc.). This, however, makes the stat
call unusable for it.
We should probably find a way how to pass an information there is a MTD device under the driver and that we should access it with a standard MTDIOC_GEOMETRY
ioctl to obtain the required information and pass them to the user.
