You can do:
*swap_vnodes::array "struct vnode *" 0t2048 | /Kn | ::grep .

Hi folks,
I met a problem when investigating the swap code. There is an array
called swap_vnodes[],which contains pointers to all the swap vnodes in
system.
static struct vnode **swap_vnodes;
#define MAX_SWAP_VNODES 2048
While this is a pointer to pointer,I would like to dump the array and
see which slots are already allocated.
mdb -k
swap_vnodes:
swap_vnodes: fffffffecc47e000
fffffffecc47e000::array "struct vnode *" 0t2048 p|::eval <p/K
0xfffffffecc47e000: 0

......
fffffffecc47e000::array "struct vnode *" 0t2048 p|::eval <p/K|::grep .!=0
sh: =0: not found
mdb: syntax error on line 1 of (pipeline) near ":"
fffffffecc47e000::array "struct vnode *" 0t2048 p|::eval <p/K|::grep .==0

0xfffffffecc47e000/K|::grep .!=0
sh: =0: not found
0xfffffffecc47e000/K|::grep .==0
0
My two questions:
1) It seems that != is not supported in mdb, so how can I specify "not
equal" in mdb?
2) While == works, it doesn't work for the above case, I guess it is
related to "/K", is there any way to work around it or do we need to fix it?
Thanks,
Zhijun
