When lio_listio() is called with LIO_NOWAIT and a non-NULL sig, and no I/O could be queued (or all entries are LIO_NOP/NULL), the completion notification dereferences a NULL aiocbp picked from an empty iteration, crashing nxsig_notification(). Scan the list for any non-NULL entry before delivering the notification, and skip it entirely when the list contains only NULL entries. Signed-off-by: zhengyu16 <zhengyu16@xiaomi.com> |
