[PATCH 08/22] staging: erofs: kill CONFIG_EROFS_FS_IO_MAX_RETRIES

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



CONFIG_EROFS_FS_IO_MAX_RETRIES seems a runtime setting
and users have no idea about the change in behaviour.

Let's remove the setting currently and fold it into code,
turn it into a module parameter if it's really needed.
