NAME
ffs - find first set bit
SYNOPSIS
#include <strings.h>
int ffs(int i);
DESCRIPTION
The ffs() function shall find the first bit set (beginning with the least significant bit) in i, and return the index of that bit. Bits are
numbered starting at one (the least significant bit).
RETURN VALUE
The ffs() function shall return the index of the first bit set. If i is 0, then ffs() shall return 0.

We have an assignment to critique Mckusic'sk paper A Fast File System for Unix http://www.cs.berkeley.edu/~brewer/cs262/FFS.pdf. As a part of the paper we are supposed to regenerate the values found in Table 1 and Table 2a and 2b using linux. My problem is how should I regenerate these results... (2 Replies)
