In JBD2 jbd2_journal_write_commit_record(), clear the buffer_ordered flag for the bh after barried IO has succeed. This prevents later, if the same buffer head were submitted to the underlying device, which has been reconfigured to not support barrier request, the JBD2 commit code could treat it as a normal IO (without barrier). This is a port from JBD/ext3 fix from Neil Brown. More details from Neil: Some devices - notably dm and md - can change their behaviour in response to BIO_RW_BARRIER requests. They might start out accepting such requests but on reconfiguration, they find out that they cannot any more. JBD2 deal with this by always testing if BIO_RW_BARRIER requests fail with EOPNOTSUPP, and retrying the write requests without the barrier (probably after waiting for any pending writes to complete). However there is a bug in the handling this in JBD2 for ext4 . When ext4/JBD2 to submit a BIO_RW_BARRIER request, it sets the buffer_ordered flag on the buffer head. If the request completes successfully, the flag STAYS SET. Other code might then write the same buffer_head after the device has been reconfigured to not accept barriers. This write will then fail, but the "other code" is not ready to handle EOPNOTSUPP errors and the error will be treated as fatal.

We cannot start transaction in ext4_direct_IO() and just let it last during the whole write because dio_get_page() acquires mmap_sem which ranks above transaction start (e.g. because we have dependency chain mmap_sem->PageLock->journal_start, or because we update atime while holding mmap_sem) and thus deadlocks could happen. We solve the problem by starting a transaction separately for each ext4_get_block() call. We *could* have a problem that we allocate a block and before its data are written out the machine crashes and thus we expose stale data. But that does not happen because for hole-filling generic code falls back to buffered writes and for file extension, we add inode to orphan list and thus in case of crash, journal replay will truncate inode back to the original size.

In order to prevent a circular locking dependency when an unlink operation is racing with an ext4 migration, we delay taking i_data_sem until just before switch the inode format, and use i_mutex to prevent writes and truncates during the first part of the migration operation.

The ext3 root inode was treated specially with respect to in-inode extended attributes, for reasons detailed in the removed comment below. The first mkfs-created inodes would not get extra_i_size or the EXT3_STATE_XATTR flag set in ext3_read_inode, which disallowed reading or setting in-inode EAs on the root. However, in ext4, ext4_mark_inode_dirty calls ext4_expand_extra_isize for all inodes; once this is done EAs may be placed in the root ext4 inode body. But for reasons above, it won't be found after a reboot. testcase: setfattr -n user.name -v value mntpt/ setfattr -n user.name2 -v value2 mntpt/ umount mntpt/; remount mntpt/ getfattr -d mntpt/ name2/value2 has gone missing; debugfs shows it in the inode body, but it is not found there by getattr. The following fixes it up; newer mkfs appears to properly zero the inodes, so this workaround isn't needed for ext4.

The buffer head pointer passed to journal_wait_on_commit_record() could be NULL if the previous journal_submit_commit_record() failed or journal has already aborted. Looking at the jbd2 debug messages, before the oops happened, the jbd2 is aborted due to trying to access the next log block beyond the end of device. This might be caused by using a corrupted image. We need to check the error returns from journal_submit_commit_record() and avoid calling journal_wait_on_commit_record() in the failure case.

Add support for different number of page table levels dependent on the highest address used for a process. This will cause a 31 bit process to use a two level page table instead of the four level page table that is the default after the pud has been introduced. Likewise a normal 64 bit process will use three levels instead of four. Only if a process runs out of the 4 tera bytes which can be addressed with a three level page table the fourth level is dynamically added. Then the process can use up to 8 peta byte.

There are two problems in the vt220 intialization: o Currently the vt220 console looses early printk events until the the vt220 tty is registered. o console should work if tty_register fails sclp_vt220_con_init calls __sclp_vt220_init and register_console. It does not register the driver with the sclp core code via sclp_register. That results in an sclp_send_mask=0. Therefore, __sclp_vt220_emit will reject buffers with EIO. Unfortunately register_console will cause the printk buffer to be sent to the console and, therefore, every early message gets dropped. The sclp_send_mask is set later during boot, when sclp_vt220_tty_init calls sclp_register. The solution is to move the sclp_register call from sclp_vt220_tty_init to __sclp_vt220_init. This makes sure that the console is properly registered with the sclp subsystem before the first log buffer messages are passed to the vt220 console. We also adopt the cleanup on error to keep the console alive if tty_register fails. Thanks to Peter Oberparleiter and Heiko Carstens for review and ideas for improvement.
