If we have to drop the Centos 7.4, this have to be explicit and
especially on this page.

I don't know the downstream impacts of that choice.

hi ceph-{maintainers,users,developers},
recently, i ran into an issue[0] which popped up when we build Ceph on
centos 7.5, but test it on centos 7.4. as we know, the gperftools-libs
package provides the tcmalloc allocator shared library, but centos 7.4
and centos 7.5 ship different version of gperftools-{devel,libs}. the
former ships 2.4, and the latter 2.6.1.
the crux is that the tcmalloc in gperftools 2.6.1 implements more
standard compliant C++ APIs, which were missing in gperftools 2.4.
that's why we have failures like:
ceph-osd: symbol lookup error: ceph-osd: undefined symbol: _ZdaPvm
when testing Ceph on centos 7.4.
my question is: is it okay to drop the support of centos/rhel 7.4? so
we will solely build and test the supported Ceph releases (luminous,
mimic) on 7.5 ?
thanks,
