access.2: Note that access() may also fail for FUSE
...
Since in some cases (e.g. libguestfs's guestmount) it also has the
semantics where files can appear owned by root, but are actually
mutable by the user, despite what one might infer from the Unix
permissions.

mmap.2: Add note about partial page in BUGS section
...
This adds a note about Linux behavior with partial page at the end
of the object. The problem here is that a page that contains only
part of a file (because the file size is not multiple of PAGE_SIZE)
stays in page cache even after the mapping is unmapped and the file
is closed. So if some process dirties such page, other mappings
will see the changes rather than zeroes.
I've also attached a reproducer which is a stripped down version of
the LTP test. The child creates a file of the size of PAGE_SIZE/2,
maps it, changes the content after the PAGE_SIZE/2. The parent
waits for the child to exit, maps the same file, and checks the
content after PAGE_SIZE/2. Uncommenting the msync() makes the test
succeed.
