Hi ,
I think this code shuld not be inside spin lock
1. if(!PageLocked(cq->async_page)){
lock_page(page);
As this puts the daemon in sleep,
As i experianced this in my code ,
I had gone through the code of lock_page,
It try to set the PG_locked bit and if already set
then
only puts the process to block,which i'm checking in
if loop.
2.While in unlock_page i got the core dump
saying
kernel BUG at filemap.c:891
EIP is at unlock_page
if somebody has clue of this please let me know.
Thanks
Prasanna
