unitialized return value in mm/mlock.c: __mlock_vma_pages_range()
Fix an unitialized return value when compiling on parisc (with CONFIG_UNEVICTABLE_LRU=y): mm/mlock.c: In function `__mlock_vma_pages_range': mm/mlock.c:165: warning: `ret' might be used uninitialized in this function Signed-off-by: Helge Deller <deller@gmx.de> [ It isn't ever really used uninitialized, since no caller should ever call this function with an empty range. But the compiler is correct that from a local analysis standpoint that is impossible to see, and fixing the warning is appropriate. ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
