bpftrace reports parse error on arm64:
"parse error:
8@x0 4@[x21, #:lo12:.LANCHOR2]
"
using "nr" to override the default constraints string can fix this.
//the default is:
stapsdt 0x0000004b NT_STAPSDT (SystemTap probe descriptors)
Provider: spdk
Name: nvmf_tgt_state
Location: 0x000000000006e664, Base: 0x00000000001ca6f0, Semaphore: 0x0000000000000000
Arguments: 8@x0 4@[x21, #:lo12:.LANCHOR2]
//using "nr" as the constraints string:
stapsdt 0x00000036 NT_STAPSDT (SystemTap probe descriptors)
Provider: spdk
Name: nvmf_tgt_state
Location: 0x000000000006f680, Base: 0x00000000001cb730, Semaphore: 0x0000000000000000
Arguments: 8@x0 4@x1
