[PATCH] module: remove redundant module_sysfs_initialized variable

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

 



The variable module_sysfs_initialized is used for checking whether
module_kset has been initialized. Checking module_kset itself works
just fine for that.
