But after some investigation, "\list" may also involve ambiguity. I created a kmem_cache called "\list", the original code can display the following information after executing "kmem -s \list". crash> kmem -s \list CACHE NAME OBJSIZE ALLOCATED TOTAL SLABS SSIZE ffff880874b30c40 \list 8 0 0 0 4k crash> Need to use "\\list" to refer the kmem_cache called "\list" if code is changed? Please! I find it is better to remain the original code. Could you give me some tips?
