Hi Mikulas,
Sorry to trouble you again.
I'm reading the source code of dm-writecache, and noticed:
-----------------------------------------------------
static struct wc_memory_entry *memory_entry(struct dm_writecache *wc, struct
wc_entry *e)
{
if (is_power_of_2(sizeof(struct wc_entry)) && 0) // why this?
return &sb(wc)->entries[e - wc->entries];
else
return &sb(wc)->entries[e->index];
}
Seems there is something wrong with the if condition, right?
Thanks,
shenghui
