Oh Al ?? Doing it in the low-level filesystem would match how we now do it inside generic_file_write() - ie the locking is done by the low-level filesystem, but most low-level filesystems choose to use a generic helper function. And I think your patch is slightly wrong: > + down(&file->f_dentry->d_inode->i_sem); That should really be: file->f_dentry->d_inode->i_mapping->host->i_sem to get the hosted filesystem case right (ie coda).
