Miklos Szeredi 93bb3d8d4c virtiofsd: remove symlink fallbacks ... Path lookup in the kernel has special rules for looking up magic symlinks under /proc. If a filesystem operation is instructed to follow symlinks (e.g. via AT_SYMLINK_FOLLOW or lack of AT_SYMLINK_NOFOLLOW), and the final component is such a proc symlink, then the target of the magic symlink is used for the operation, even if the target itself is a symlink. I.e. path lookup is always terminated after following a final magic symlink. I was erronously assuming that in the above case the target symlink would also be followed, and so workarounds were added for a couple of operations to handle the symlink case. Since the symlink can be handled simply by following the proc symlink, these workardouds are not needed. Also remove the "norace" option, which disabled the workarounds. Commit bdfd667883 ("virtiofsd: Fix xattr operations") already dealt with the same issue for xattr operations.
