This is the file actually read at boot time by grub. /Bruce ^ permalink raw reply [flat|nested] 10+ messages in thread

You can always get a hugetlbfs mount of a particular hugepage size by passing the pagesize= parameter when doing the mount. /Bruce ^ permalink raw reply [flat|nested] 10+ messages in thread
