Mostly header changes associated with #ifdef __KERNEL__ stuff.
Some function prototypes had to be reordered to separate
shared and kernel only functions.
One thing I don't have clear confirmation on yet is this change:
static inline int xfs_lowbit32(__uint32_t v)
{
- unsigned long t = v;
- return (v) ? find_first_bit(&t, 32) : -1;
+ return ffs(v) - 1;
}
