Choose Y or M here to include support for mounting the
experimental Ceph distributed file system. Ceph is an extremely
scalable file system designed to provide high performance,
reliable access to petabytes of storage.
More information at https://ceph.io/.
If unsure, say N.

depends on CEPH_FS
default n
help
Inline data support has been deprecated in the CephFS MDS
and is being formally removed. Existing inline data can be
migrated to data pool objects via MDS scrub. Choose N
unless you have a legacy filesystem that requires it,
and ensure all inline data has been migrated (see
ceph fs set <fs> inline_data false) before enabling.

Choose Y here to enable persistent, read-only local
caching support for Ceph clients using FS-Cache

bool "Ceph POSIX Access Control Lists"
depends on CEPH_FS
select FS_POSIX_ACL
help
POSIX Access Control Lists (ACLs) support permissions for users and
groups beyond the owner/group/world scheme.
If you don't know what Access Control Lists are, say N
config CEPH_FS_SECURITY_LABEL
bool "CephFS Security Labels"
depends on CEPH_FS && SECURITY
help
Security labels support alternative access control models
implemented by security modules like SELinux. This option
enables an extended attribute handler for file security
labels in the Ceph filesystem.
If you are not using a security module that requires using
extended attributes for file security labels, say N.
