| Subject: module: Remove module size limit |
| |
| From: Sasha Levin <levinsasha928@gmail.com> |
| |
| commit f946eeb9313ff1470758e171a60fe7438a2ded3f upstream. |
| |
| Module size was limited to 64MB, this was legacy limitation due to vmalloc() |
| which was removed a while ago. |
| |
| Limiting module size to 64MB is both pointless and affects real world use |
| cases. |
