RE: Kernel modules

["Patwardhan, Aniruddha" <Aniruddha_Patwardhan@bmc.com>]

Hi SP,

For a given kernel (at least in your case "sys_call_table_Rdfdb18bd" is same
as "sys_call_table". 
"Rdfdb18bd" is the versioning information, which is calculated for each
symbol when we export it using
EXPORT_SYMBOL macro. 

If we didn't want the versioning info to be appended to symbol we can use
EXPORT_SYMBOL_NOVERS

Hi,
I have written a user-level program which requires a
pointer to sys_call_table. I invoke query_module
function with name as NULL & the value of 'which' as
QM_SYMBOLS, thus trying to get kernel symbols. 

query_module returns a pointer to symbol with name
"sys_call_table_Rdfdb18bd". Is this the same as
sys_call_table ? What is the number at the end of the
symbol ?

Thanks,
SP
