kjournald starting. Commit interval 5 seconds EXT3-fs (dasdb1): using internal journal

Did not observe this with next-20100205. Also there doesn't seem to be any patches applied to this code after the last release. So not sure what could have caused this. Corresponding code is :

664 if (atomic_read(&dentry->d_count) != 0) {
665 printk(KERN_ERR

666                                        "BUG: Dentry %p{i=%lx,n=%s}"
667                                        " still in use (%d)"
668                                        " [unmount of %s %s]\n",
669                                        dentry,
670                                        dentry->d_inode ?
671                                        dentry->d_inode->i_ino : 0UL,
672                                        dentry->d_name.name,
673                                        atomic_read(&dentry->d_count),
674                                        dentry->d_sb->s_type->name,
675                                        dentry->d_sb->s_id);
676                                 BUG();
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

677 }

Let me know if i can provide any other information. Have attached the config.

Thanks

While running hackbench against today's next-20100208 (9056d31..) on a s390 box, came across following BUG.

I can still recreate this issue against next-20100210.

EXT3-fs (dasdb1): mounted filesystem with writeback data mode

BUG: Dentry 00000000fbde0ec0{i=13c39,n=bin} still in use (1) unmount of ext3 da

Did not observe this with next-20100205. Also there doesn't seem to be any patches applied to this code after the last release. So not sure what could have caused this. Corresponding code is :

664 if (atomic_read(&dentry->d_count) != 0) {
665 printk(KERN_ERR

666                                        "BUG: Dentry %p{i=%lx,n=%s}"
667                                        " still in use (%d)"
668                                        " [unmount of %s %s]\n",
669                                        dentry,
670                                        dentry->d_inode ?
671                                        dentry->d_inode->i_ino : 0UL,
672                                        dentry->d_name.name,
673                                        atomic_read(&dentry->d_count),
674                                        dentry->d_sb->s_type->name,
675                                        dentry->d_sb->s_id);
676                                 BUG();
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

677 }

Let me know if i can provide any other information. Have attached the config.

Thanks
