[PATCH v2] vfs: return -EOVERFLOW in generic_remap_checks() when overflow check fails

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Keep the errno value consistent with the equivalent check in
generic_copy_file_checks() that returns -EOVERFLOW, which feels like the
more appropriate value to return compared to the overly generic -EINVAL.
