journalctl --no-pager | grep "csum failed ino"

I'm not sure from journalctl's man page what a 'SYSLOG IDENTIFIER' is, but if
'csum failed ino' is one you could do:

journalctl --no-pager -t 'csum failed ino'

I don't know if these are generated by the kernel or by btrfsd or some other
unit; once we know what unit is involved you could use -u btrfs or similar.
