...nt to the instrumented one. After instrumentation is done, the target
driver may start executing.
If some original function of the driver contained, say,
mov 0xabcd (%rax), %rsi
mov %rbx, 0xbeeffeed (%rsi)
that will be transformed to something like
lea 0xabcd (%rax), %rbx
mov %rbx, <local_storage1>
mov 0xabcd (%rax), %rsi
lea 0xbeeffeed (%rsi), %rbx
mov %rbx, <local_storage2>
mov %rbx, 0xbeeffeed (%rsi)

enable/disable shared namespace in passdb
hello all
i'm currently using passdb to enable and disable various namespaces
conditionally : for example the following work
namespace/inbox/inbox=no

namespace/local_storage/disabled=no
namespace/comboINBOX_local_pfso/disabled=no
namespace/comboINBOX_local_pfso/inbox=yes
but i can't get things like the following to work

Oh, that works on a completely different way than I even imagined,
a whole another level of complexity.
