[PATCH] libext2fs: don't break when ext2fs_clear_generic_bmap() for 32-bit bitmaps

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is only an issue for programs compiled against e2fsprogs 1.41
that manipulate bitmaps directly.  Fortunately there are very few
programs which do that, especially those that try to clear a bitmap.
