# handling of object-specific CFLAGs, CFLAGS_$(object) has changed. Prior to

# commit, it is now required to give Kbuild relative paths along-with the

|
|
# object name (CFLAGS_<somepath>/somefile.o>). As a result, CFLAGS_$(object)
|
|
|
|

# is set twice, once with a relative path to the object files and once with
