Name:pcpu_chunk_refresh_hint - updates metadata about a chunk*@chunk: chunk of interest*@full_scan: if we should scan from the beginning* Iterates over the metadata blocks to find the largest contig area
Proto:static void pcpu_chunk_refresh_hint(struct pcpu_chunk *chunk, bool full_scan)
Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
struct pcpu_chunk * | chunk | |
bool | full_scan |
724 | If Not full_scan && scan hint for block Then |
726 | lock relative startingposition of the contig hint = lock relative startingposition of the scan hint |
728 | scan hint for block = 0 |
729 | Else |
731 | contig hint for block = 0 |
734 | bits = 0 |
