to some of their USB interfaces.  The data gets stuck in the TTYs queue

error recovery when registering LUN's devices.

First of all, when device_register() fails the device still

fsg->ref reference counter the counter must be incremented

Second of all, after any of the device_create_file()s fails,
device_unregister() is called which in turn (indirectly) calls
lun_release() which decrements fsg->ref.  So, again, the
reference counter must be incremented beforehand.

Lastly, if the first or the second device_create_file()
succeeds, the files are never removed.  To fix it,
device_remove_file() needs to be called.  This is done by
simply marking LUN as registered prior to creating files so
that fsg_unbind() can handle removing files.

Only mips, s390, and score set CONFIG_32BIT for 32-bit builds, so fix it for

UINT_MAX bytes and shift them down to pages (so with a possible "+1" for

Btrfs: deal with errors from updating the tree log

During unlink we remove any references to the inode from
the tree log.  It can return -ENOENT and other errors,

14 years agox86: Check irq_remapped instead of remapping_enabled in destroy_irq()

x86: Check irq_remapped instead of remapping_enabled in destroy_irq()

Russ Anderson reported:
| There is a regression that is causing a NULL pointer dereference
| in free_irte when shutting down xpc. git bisect narrowed it down
| to git commit d585d06(intr_remap: Simplify the code further), which
| changed free_irte(). Reverse applying the patch fixes the problem.

We need to use irq_remapped() for each irq instead of checking only
intr_remapping_enabled as there might be non remapped irqs even when
remapping is enabled.

[ tglx: use cfg instead of retrieving it again. Massaged changelog ]
