This patch optimizes the tracepoint by replacing these hardcoded strings with a new enumeration f2fs_cp_phase. 1.Defines enum f2fs_cp_phase with values for each checkpoint phase. 2.Updates trace_f2fs_write_checkpoint to accept a u16 phase argument instead of a string pointer. 3.Uses __print_symbolic in TP_printk to convert the enum values back to their corresponding strings for human-readable trace output. This change reduces the storage overhead for each trace event by replacing a variable-length string with a 2-byte integer, while maintaining the same readable output in ftrace.
