Re: [Crash-utility] dis command not correct in crash [ ARM only ]

But in 3.1.1, the "task_rq_lock" function is renamed to "task_rq_lock.isra.123": crash> dis task_rq_lock symbol not found: task_rq_lock possible alternatives: c0015c60 (t) task_rq_lock.isra.123 crash> which is also reflected in the vmlinux file: crash> !nm -Bn vmlinux | grep task_rq_lock c0015c60 t task_rq_lock.isra.123 crash> I don't know what "isra" means, but it disassembles OK when used like this: crash> dis task_rq_lock.isra.123 0xc0015c60 <task_rq_lock.isra.123>: push {r11, lr} 0xc0015c64 <task_rq_lock.isra.123+4>: add r11, sp, #4 0xc0015c68 <task_rq_lock.isra.123+8>: mrs r3, CPSR 0xc0015c6c <task_rq_lock.isra.123+12>: orr r2, r3, #128 ; 0x80 0xc0015c70 <task_rq_lock.isra.123+16>: msr CPSR_c, r2 0xc0015c74 <task_rq_lock.isra.123+20>: str r3, [r0] 0xc0015c78 <task_rq_lock.isra.123+24>: mov r0, #1 0xc0015c7c <task_rq_lock.isra.123+28>: bl 0xc0015ba4 <add_preempt_count> 0xc0015c80 <task_rq_lock.isra.123+32>: mov r0, #1 0xc0015c84 <task_rq_lock.isra.123+36>: bl 0xc0015ba4 <add_preempt_count> 0xc0015c88 <task_rq_lock.isra.123+40>: ldr r0, [pc, #0] ; 0xc0015c90 <task_rq_lock.isra.123+48> 0xc0015c8c <task_rq_lock.isra.123+44>: pop {r11, pc} 0xc0015c90 <task_rq_lock.isra.123+48>: eorsgt lr, r12, r0, asr r2 crash> And interestingly enough, gdb accepts the symbol without the "isra.123", strips it from the text symbol, and it looks like this: crash> disass task_rq_lock Dump of assembler code for function task_rq_lock: 0xc0015c60 <+0>: push {r11, lr} 0xc0015c64 <+4>: add r11, sp, #4 0xc0015c68 <+8>: mrs r3, CPSR 0xc0015c6c <+12>: orr r2, r3, #128 ; 0x80 0xc0015c70 <+16>: msr CPSR_c, r2 0xc0015c74 <+20>: str r3, [r0] 0xc0015c78 <+24>: mov r0, #1 0xc0015c7c <+28>: bl 0xc0015ba4 <add_preempt_count> 0xc0015c80 <+32>: mov r0, #1 0xc0015c84 <+36>: bl 0xc0015ba4 <add_preempt_count> 0xc0015c88 <+40>: ldr r0, [pc, #0] ; 0xc0015c90 <task_rq_lock+48> 0xc0015c8c <+44>: pop {r11, pc} 0xc0015c90 <+48>: eorsgt lr, r12, r0, asr r2 End of assembler dump. crash>
