However, In the "matrix" environment, 10.1/0.1 was calculated as 100. Would you give me some answers? Sincerely Kazuki Sakura [[alternative HTML version deleted]]

Hi All, on fresh installation of 10.0-BETA3 it is unable to access files on Samba share: # mount [...] //USER at HOSTING/DTEL-IX on /mnt/fs/dtel-ix (smbfs) # cp /mnt/fs/dtel-ix/port_distribution.xls ./ cp: ./port_distribution.xls: Bad address At the same time I get kernel messages: smbfs_getpages: error 60 vm_fault: pager read error, pid 927 (cp) Please advice, thanks. -- MINO-RIPE

...lock into two fine-grained inflate_lock and deflate_lock, and eliminates the unnecessary use of the shared data (i.e. vb->pnfs, vb->num_pfns). This enables leak_balloon and fill_balloon to run concurrently and solves the deadlock issue.
