[PATCH v2 -next] mm/slub: remove dummy slabinfo functions

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

 



From: Xiu Jianfeng <xiujianfeng@xxxxxxxxxx>

The SLAB implementation has been removed since 6.8, so there is no
other version of slabinfo_show_stats() and slabinfo_write(), then we
can remove these two dummy functions.
