Konstantin Belousov 9ded9474d3 Do not coalesce if the swap object belongs to tmpfs vnode. The ... coalesce would extend the object to keep pages for the anonymous mapping created by the process. The pages has no relations to the tmpfs file content which could be written into the corresponding range, causing anonymous mapping and file content aliasing and subsequent corruption. Another lesser problem created by coalescing is over-accounting on the tmpfs node destruction, since the object size is substracted from the total count of the pages owned by the tmpfs mount.
