There was a problem hiding this comment.
nit, as we have 4 different error_code.cc implementations throughout the repo we should probably use "osdc/error_code.cc" in the commit message.
Fix AddressSanitizer ODR (One Definition Rule) violation caused by
osdc/error_code.cc being compiled into both the osdc library and
ceph-common library.
The violation occurred because osdc_error_category was defined in
both the rbd binary (via osdc) and libceph-common.so, creating
duplicate symbols at runtime.
Since all targets that link against osdc also link against
ceph-common, removing osdc/error_code.cc from osdc doesn't break the
build while eliminating the duplicate definition.
ASan error sample:
