Actually according to the output this is a read-time corruption. THis
means the corrupted data has already been written to disk, likely by an
older kernel that didn't have the tree cherk code. So running a memcheck
is still useful to prevent future corruption.
As far as the corrupted files goes - well its data is corrupted. It can
technically be fixed, but you'd have to do it yourself. Or alternatively
go back on an older kernel i.e pre- 5.11 and try to copy that particular
file (inode 2394634).
