| |
Use kstrdup when the goal of an allocation is copy a string into the allocated region.
The semantic patch that makes this change is as follows: // <smpl> @@ expression from,to; expression flag,E1,E2; statement S; @@
- to = kmalloc(strlen(from) + 1,flag); + to = kstrdup(from, flag); ... when != \(from = E1 \| to = E1 \) if (to==NULL || ...) S ... when != \(from = E2 \| to = E2 \) - strcpy(to, from); // </smpl>
