include/linux/slab.h:730: warning: Function parameter or struct member '_size' not described in 'kcalloc'
include/linux/slab.h:730: warning: Function parameter or struct member '_flags' not described in 'kcalloc'
include/linux/slab.h:730: warning: Excess function parameter 'n' description in 'kcalloc'
include/linux/slab.h:730: warning: Excess function parameter 'size' description in 'kcalloc'
include/linux/slab.h:730: warning: Excess function parameter 'flags' description in 'kcalloc'
