__BITMAP_SHIFT_LEFT(9)            Basic Kernel Library Functions           __BITMAP_SHIFT_LEFT(9)



NAME
       __bitmap_shift_left - logical left shift of the bits in a bitmap

SYNOPSIS
       void __bitmap_shift_left(unsigned long * dst, const unsigned long * src,
                                unsigned int shift, unsigned int nbits);

ARGUMENTS
       dst
           destination bitmap

       src
           source bitmap

       shift
           shift by this many bits

       nbits
           bitmap size, in bits

DESCRIPTION
       Shifting left (multiplying) means moving bits in the LS -> MS direction. Zeros are fed
       into the vacated LS bit positions and those MS bits shifted off the top are lost.
