instrumented.h: Fix all kernel-doc format warnings
Fix 26 kernel-doc notation warnings by converting the function documentation to kernel-doc format. Warning example: instrumented.h:155: warning: Function parameter or member 'to' not described in 'instrument_copy_from_user_after' instrumented.h:155: warning: Function parameter or member 'from' not described in 'instrument_copy_from_user_after' instrumented.h:155: warning: Function parameter or member 'n' not described in 'instrument_copy_from_user_after' instrumented.h:155: warning: Function parameter or member 'left' not described in 'instrument_copy_from_user_after' Fixes: 36e4d4dd4fc4 ("include/linux: Add instrumented.h infrastructure") Fixes: 00047c2e6d7c ("instrumented.h: Introduce read-write instrumentation hooks") Fixes: 33b75c1d884e ("instrumented.h: allow instrumenting both sides of copy_from_user()") Fixes: 888f84a6da4d ("x86: asm: instrument usercopy in get_user() and put_user()") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Marco Elver <elver@google.com> Cc: Alexander Potapenko <glider@google.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Dmitry Vyukov <dvyukov@google.com> Cc: Paul E.
