<div dir="ltr">Dear Phil,<div><br></div><div>We think it's some kind of deadlock situation.</div><div><br>During reconnecting, first BIO sets pending_bitmap_work.n to 1 and waits for status until changing from WFBitMapS to SyncSource.<br>At this time, If another BIO exists, this second BIO waits until pending_bitmap_work.n to zero at inc_ap_bio().<br>Because status is unchanged in WFBitMapS, pending_bitmap_work.n can not be zero forever.</div><div><br>Why doesn't the status change from WFBitMapS to SyncSource for the first BIO?
