Review Comment:
@acassis ,Thank you for your review and feedback. The parameters of the
memdump command are passed down via the memdump_write method, with the relevant
code in this method as follows:
struct mm_memdump_s dump =
{
PID_MM_ALLOC,
#if CONFIG_MM_BACKTRACE >= 0
0,
ULONG_MAX
#endif
};
The type of mm_memdump_s is struct malltask, whose definition is shown below:
struct malltask
{
pid_t pid; /* Process id */
#if CONFIG_MM_BACKTRACE >= 0
unsigned long seqmin; /* The minimum sequence */
unsigned long seqmax; /* The maximum sequence */
#endif
};
To maintain consistency with the previous data types, I also use unsigned
long for seqmin and seqmax here.
