           Summary: KALLSYMS doesn't decode DEBUG_SPINLOCK printks
    Kernel Version: 2.5.59-bk4
            Status: NEW
          Severity: low
             Owner: bugme-janitors at lists.osdl.org

Distribution: Debian Testing
Hardware Environment: single x86 CPU
Software Environment:  
CONFIG_KALLSYMS=y
CONFIG_DEBUG_KERNEL=y
CONFIG_DEBUG_STACKOVERFLOW=y
CONFIG_DEBUG_SLAB=y
CONFIG_DEBUG_IOVIRT=y
CONFIG_DEBUG_SPINLOCK=y
CONFIG_DEBUG_SPINLOCK_SLEEP=y

Problem Description:

When compiling with KALLSYMS and DEBUG_SPINLOCK (or maybe its 
DEBUG_SPINLOCK_SLEEP), kallsyms doesn't decode the spinlock prinkts. I don't 
know if this is by design or not, but it is inconsistant with kallsyms's 
decoding of oops/bugs... but a very minor complaint, either way :)

Steps to reproduce:

The debug spinlock config option produces output like this:
sound/oss/ad1848.c:1410: spin_lock(sound/oss/ad1848.c:c03c8aa0) already locked 
by sound/oss/ad1848.c/988
sound/oss/ad1848.c:219: spin_lock(sound/oss/ad1848.c:c03c8aa0) already locked 
by sound/oss/ad1848.c/1410
sound/oss/ad1848.c:1435: spin_unlock(sound/oss/ad1848.c:c03c8aa0) not locked
sound/oss/ad1848.c:1010: spin_unlock(sound/oss/ad1848.c:c03c8aa0) not locked
sound/oss/ad1848.c:329: spin_lock(sound/oss/ad1848.c:c03c8aa0) already locked 
by sound/oss/ad1848.c/1143
sound/oss/ad1848.c:219: spin_lock(sound/oss/ad1848.c:c03c8aa0) already locked 
by sound/oss/ad1848.c/351
sound/oss/ad1848.c:367: spin_unlock(sound/oss/ad1848.c:c03c8aa0) not locked
sound/oss/ad1848.c:1187: spin_unlock(sound/oss/ad1848.c:c03c8aa0) not locked

Is it possible to get kallsyms to decode c03c8aa0?

c03c8aa0 d ad1848_lock
