so you've got ext3. Nothing changed in the VFS or in ext3 in -git yet.
the instruction pattern:
Code: f6 43 04 10 75 06 f0 ff 03 48 89 d8 fe 43 08 eb 31 fe 43 08 48 8b
45 d0 48 8b 00 48 89 45 d0 48 8b 45 d0 48 85 c0 74 18 48 89 c2 <48> 8b
00 48 8d 5a e8 44 39 73 30 0f 18 08 75 d9 e9 6a ff ff ff
========
shows that you've got "prefetchnta (%esi)" indirect:
0f 18 00 prefetcht0 (%eax)
so the prefetch instructions are patched in, neither the compiler nor
the CPU should ignore them.
