Regarding code part in ext4


Hi,

I am trying to understand ext4 code and I got stuck in search of finding the the functionality of trace_ext4_ext_map_blocks_enter() other related functions. I am not able to find the definitions of it to understand the functionalities of the same. Can any body five little info about those ?

you will find trace_<function>_enter() to trace the beginning of the function, and similarly trace_<function>_exit() at the end of the <function>
those are defined in trace/event/ext4.h:
