The patch titled
Subject: lib/test_bitmap.c: add bitmap_fill()/bitmap_set() test cases
has been removed from the -mm tree. Its filename was

This patch was dropped because it was merged into mainline or a subsystem tree

From: Andy Shevchenko <[email protected]>
Subject: lib/test_bitmap.c: add bitmap_fill()/bitmap_set() test cases

Explicitly test bitmap_fill() and bitmap_set() functions.

For bitmap_fill() we expect a consistent behaviour as in bitmap_zero(), i.e. the trailing bits will be set up to unsigned long boundary.
