84019b9170 noteram: when the buffer overflow happen and give the asan report 
READ of size 1 at 0x5ec78f90 thread T0
0 0x59682d7a in noteram_remove note/noteram_driver.c:432
1 0x59683c43 in sched_note_add note/noteram_driver.c:854
0x5ec78f90 is located 0 bytes to the right of global variable 'g_noteram_info' defined in 'note/noteram_driver.c:95:30' (0x5ec78780) of size 2064
0x5ec78f90 is located 48 bytes to the left of global variable '*.Lubsan_type0' defined in 'note/noteram_driver.c' (0x5ec78fc0) of size 10
reason: that read pos is tail of g_noteram_info.ni_buffer causes overflow
