In elf_strtbl_add() pointer 'strtab', which value is a result of shifting

The vDPA block simulator always allocated a 128 MiB ram-disk, but some
filesystems (e.g. XFS) may require larger minimum sizes (see

So to allow us to test these filesystems, let's add a module parameter

virtio balloon communicates to the core that in some
configurations vq #s are non-contiguous by setting name

Unfortunately, core then turned around and just made them
contiguous again. Result is that driver is out of spec.

SGX runtimes such as Gramine may implement EDMM-based lazy allocation of
enclave pages and may support MADV_DONTNEED semantics [1]. The former
implies #PF-based page allocation, and the latter implies the usage of
SGX_IOC_ENCLAVE_REMOVE_PAGES ioctl.
EDMM-based lazy allocation and MADV_DONTNEED sem
Two enclave threads may try to add and remove the same enclave page
simultaneously (e.g., if the SGX runtime supports both lazy allocation
and MADV_DONTNEED semantics). Consider some enclave page added to the
enclave. User space decides to temporarily remove this page (e.g.,
emulating the MADV_DONT
SGX_ENCL_PAGE_BEING_RECLAIMED flag is set when the enclave page is being
reclaimed (moved to the backing store). This flag however has two
logical meanings:
1. Don't attempt to load the enclave page (the page is busy).
2. Don't attempt to remove the PCMD page corresponding to this enclave
page
Imagine an mmap()'d file. Two threads touch the same address at the same
time and fault. Both allocate a physical page and race to install a PTE
for that page. Only one will win the race. The loser frees its page, but
still continues handling the fault as a success and returns
