| Subject: [PATCH] ltp: vma03 fix the alginment of page size |
| |
| the offset the param of mmap2() doesn't align the page size, but, |
| this param allow must be a multiple of the page size as returned |
| by sysconf(_SC_PAGE_SIZE).meanwhile offset * 4096 must be a |
| multiple of the system page size, so modify the input param of offset |
| pgoff = (ULONG_MAX - 1)&(~((pgsz-1)>>12)); |
