Allow users to have numeric fields displayed as log2 values in case
value range is very wide by appending '.log2' to field names.
For example,
# echo 'hist:key=bytes_req' > kmalloc/trigger
# cat kmalloc/hist
{ bytes_req: 504 } hitcount: 1
{ bytes_req: 11 } hitcount: 1
{ bytes_req: 104 } hitcount: 1
{ bytes_req: 48 } hitcount: 1
{ bytes_req: 2048 } hitcount: 1
{ bytes_req: 4096 } hitcount: 1
{ bytes_req: 240 } hitcount: 1
{ bytes_req: 392 } hitcount: 1
{ bytes_req: 13 } hitcount: 1
{ bytes_req: 28 } hitcount: 1
{ bytes_req: 12 } hitcount: 1
{ bytes_req: 64 } hitcount: 2
{ bytes_req: 128 } hitcount: 2
{ bytes_req: 32 } hitcount: 2
{ bytes_req: 8 } hitcount: 11
{ bytes_req: 10 } hitcount: 13
{ bytes_req: 24 } hitcount: 25
{ bytes_req: 160 } hitcount: 29
{ bytes_req: 16 } hitcount: 33
{ bytes_req: 80 } hitcount: 36
When using '.log2' modifier, the output looks like:
# echo 'hist:key=bytes_req.log2' > kmalloc/trigger
# cat kmalloc/hist
{ bytes_req: ~ 2^12 } hitcount: 1
{ bytes_req: ~ 2^11 } hitcount: 1
{ bytes_req: ~ 2^9 } hitcount: 2
{ bytes_req: ~ 2^6 } hitcount: 3
{ bytes_req: ~ 2^3 } hitcount: 13
{ bytes_req: ~ 2^5 } hitcount: 19
{ bytes_req: ~ 2^8 } hitcount: 49
{ bytes_req: ~ 2^7 } hitcount: 57
{ bytes_req: ~ 2^4 } hitcount: 74
