Hi,
The max value of lpfc_log_verbose is intended to be 0xffffffff, but since
it was treated as int, 0xffffffff was not actually accepted. Correcting
it to the actual max value (0x7fffffff) (Bits up to 18th are defined and
bits up to 15th are actually used today.)
This is the message when tried to store 0xffffffff to lpfc_log_verbose.
kernel: lpfc 0000:02:03.0: 0:(0):0424 lpfc_log_verbose attribute cannot be set to -1, allowed range is [0x0, 0xffffffff]
Changing its type from 'int' to 'unsigned int' might be another option.
