rename.2: Minor wording fix
...
The meaning of "when overwriting" is not clear. I believe what is
meant is that when an existing 'newpath' is replaced. However, we
can convey that meaning by eliding this text with the preceding
paragraph, so this patch does that.

Relocate text noting that there may be a window when 'oldpath' and

belong near the text noting that an existing 'newpath' will be
atomically replaced. (In ancient versions of the page, these two
pieces of text were closer together.)

rename.2: Clarify that ERRORS may cause rename to fail (not to be nonatomic)

The existing wording suggests that there are ERRORS that may cause
the operation to be nonatomic. The point is of course that there
are various restrictions on rename operations that may cause the
operation to fail.

mlock.2: Document that fork() after mlock() may be a bad idea in a RT process
...
fork() will remove the write PTE bit from the page table on each
VMA which will be copied via COW. As such, the memory is available
but marked read only in the page table and will fault on write
access. This renders the previous mlock() operation almost
useless because in a multithreaded application a realtime thread
may block on mmap_sem while a thread with low priority is holding
the mmap_sem (for instance because it is allocating memory which
needs to be mapped in).
There is actually nothing we can do to mitigate the outcome. We could
add a warning to the kernel for people that are not yet aware of the
updated documentation.
