To check a directory's in-use bitmap bit by bit, we use a pointer to an 8 bit wide unsigned value. The index used to dereference this pointer is calculated by shifting the bit index right 3 bits. Then we do a logical AND with the bit# represented by the lower 3 bits of the bit index. This is an idiomatic way of iterating through a bit map with simple bitwise operations. This commit fixes the bug that we only checked bits 3:0 of each 8 bit chunk, because we only used bits 1:0 of the bit index for the bit# in the current 8 bit value. This resulted in files not being returned by getdirentries(2). Change the type of the bit map pointer from `char *' to `u_int8_t *'. |
