Subject: ceph: show non-default options only
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ff7eeb82cc16f25203b69f817cbbb85845c817fe;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ceph: show non-default options only

Don't pollute /proc/mounts with default options (presently these are
dcache, nofsc and acl).  Leave the acl/noacl however - it's a bit of
a special case due to CONFIG_CEPH_FS_POSIX_ACL.
