Justin Lebar 04dcb3c8f8 proc.5: statm's "shared" field refers to pages backed by files 
I noticed that statm's "shared" field doesn't match the sum of
all the "shared" entries in smaps [1].

The kernel docs explain that statm's "shared" field is "number of
pages that are shared (i.e. backed by a file)" [2].  smaps appears
to call a page shared if it's mapped by at least two processes,
which explains this discrepancy.

I'm not a kernel hacker, but it appears to me they do mean "i.e."
and not "e.g." in the statm description: In
fs/proc/task_mmu.c::task_statm, I see

    *shared = get_mm_counter(mm, MM_FILEPAGES);

Here's a patch which updates the man page to match the (hopefully
correct) kernel docs.

Michael Kerrisk f9313d015c proc.5: Default for /proc/sys/fs/protected_{hardlinks,symlinks} is now 0 
The default setting of 1 in/proc/sys/fs/protected_hardlinks
and /proc/sys/fs/protected_symlinks caused one too many
breakages for Linus's taste, so commit 561ec64ae67e changed
the default for both files to 0.

Existing pages variously use "userspace or "user space".
But, "userspace" is not quite an English word.
So change "userspace" to "user space" or, when used
attributively, "user-space".
