[PATCH] mm/swap.c: fix kernel-doc functions and parameters

From: Randy Dunlap
Date: Sun Jan 28 2018 - 23:02:39 EST


From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Fix some basic kernel-doc notation in mm/swap.c:
- make function names in kernel-doc notation match the functions
- make function parameter names in kernel-doc match the actual parameters

Fix function kernel-doc to match the change in commit 67fd707f4681:
- drop the kernel-doc notation for @nr_pages from pagevec_lookup_range()
and correct the function description for that change

Fixes 67fd707f4681:
("mm: remove nr_pages argument from pagevec_lookup_{,range}_tag()")
