2020-09-30avoid the random memory barrier issue in mmap testing on Arm64Bin Lu
There is a new random issue on some Arm64 machines. This scene can be summarized as following: Sometimes, the content of the func() pointer is still 0 opcode. The probability of this kind of issue is very low, currently only available on some machines. After inserting a simple memory barrier, this issue was gone. The code to directly use the memory barrier is as follows: memcpy(reinterpret_cast<void*>(addr), machine_code, sizeof(machine_code)); isb() func = reinterpret_cast<uint32_t (*)(void)>(addr); Signed-off-by: Bin Lu <bin.lu@arm.com>

2019-03-28Clean up gofer handle caching.Jamie Liu
- Document fsutil.CachedFileObject.FD() requirements on access permissions, and change gofer.inodeFileState.FD() to honor them. Fixes #147. - Combine gofer.inodeFileState.readonly and gofer.inodeFileState.readthrough, and simplify handle caching logic. - Inline gofer.cachePolicy.cacheHandles into gofer.inodeFileState.setSharedHandles, because users with access to gofer.inodeFileState don't necessarily have access to the fs.Inode (predictably, this is a save/restore problem).
