Proto:static void __zs_unmap_object(struct mapping_area *area, struct page *pages[2], int off, int size)
Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
struct mapping_area * | area | |
struct page * | pages | |
int | off | |
int | size |
1212 | If mapping mode == ad-only (no copy-out at unmap time) Then Go to out |
1216 | buf = buf + ZS_HANDLE_SIZE |
1217 | size -= ZS_HANDLE_SIZE |
1218 | off += ZS_HANDLE_SIZE |
1224 | addr = kmap_atomic(pages[0]) |
1226 | Prevent people trying to call kunmap_atomic() as if it were kunmap()* kunmap_atomic() should get the return value of kmap_atomic, not the page.(addr) |
1227 | addr = kmap_atomic(pages[1]) |
1229 | Prevent people trying to call kunmap_atomic() as if it were kunmap()* kunmap_atomic() should get the return value of kmap_atomic, not the page.(addr) |
