| From | Joe Perches <> | Subject | [PATCH 23/27] cgroup: Remove use of seq_printf return value | Date | Sat, 21 Feb 2015 18:53:50 -0800 |
| |
The seq_printf return value, because it's frequently misused, will eventually be converted to void.
See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to seq_has_overflowed() and make public")
