Kernel panic - not syncing: Fatal exception in interruptThat oops took me to the "ackqueue" implementation in capi.c. The crash
occured in capincci_add_ack() (auto-inlined by the compiler).I read the code a bit and finally decided to replace the custom linked list
implementation (struct capiminor->ackqueue) by a struct list_head. That
did not solve the crash, but produced the following interresting oops:Unable to handle kernel paging request at virtual address 00200200

LIST_POISON2. I thought about some race condition, but as this is an UP
system, it leads to questions on how it can happen. If we look at EFLAGS:
00010202, we see that interrupts are enabled at the time of the crash
(eflags & 0x200).Finally, I don't understand all the capi code, but I think that
handle_minor_send() is racing somehow against capi_recv_message(), which
call both capiminor_del_ack(). So if an IRQ occurs in the middle of
capiminor_del_ack() and another instance of it is invoked, it leads to
linked list corruption.I came up with the following patch. With this, I could not reproduce the
crash anymore. Clearly, this is not the correct fix for the issue. As this
seems to be some locking issue, there might be more locking issues in that
code. For example, doesn't the whole struct capiminor have to be locked
somehow?Cc: Carsten Paeth

Extend the get_sb() filesystem operation to take an extra argument that
permits the VFS to pass in the target vfsmount that defines the mountpoint.The filesystem is then required to manually set the superblock and root dentry
pointers. For most filesystems, this should be done with simple_set_mnt()
which will set the superblock pointer and then set the root dentry to the
superblock's s_root (as per the old default behaviour).The get_sb() op now returns an integer as there's now no need to return the
superblock pointer.This patch permits a superblock to be implicitly shared amongst several mount
points, such as can be done with NFS to avoid potential inode aliasing. In
such a case, simple_set_mnt() would not be called, and instead the mnt_root
and mnt_sb would be set directly.The patch also makes the following changes:
(*) the get_sb_*() convenience functions in the core kernel now take a vfsmount
pointer argument and return an integer, so most filesystems have to change
very little.(*) If one of the convenience function is not used, then get_sb() should
normally call simple_set_mnt() to instantiate the vfsmount. This will
always return 0, and so can be tail-called from get_sb().(*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the
dcache upon superblock destruction rather than shrink_dcache_anon().This is required because the superblock may now have multiple trees that
aren't actually bound to s_root, but that still need to be cleaned up. The
currently called functions assume that the whole tree is rooted at s_root,
and that anonymous dentries are not the roots of trees which results in
dentries being left unculled.However, with the way NFS superblock sharing are currently set to be
implemented, these assumptions are violated: the root of the filesystem is
simply a dummy dentry and inode (the real inode for '/' may well be
inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries
with child trees.[*] Anonymous until discovered from another tree.
(*) The documentation has been adjusted, including the additional bit of
changing ext2_* into foo_* in the documentation.[akpm@osdl.org: convert ipath_fs, do other stuff]

Fix a possible Oops in the Siemens Gigaset base driver when the device is
unplugged while an ISDN connection is still active, and makes sure that the
isdn4linux link level (LL) is properly informed if a connection is broken
by the USB cable being unplugged.- Avoid unsafe checks of URB status fields outside the URB completion
handlers, keep track of in-use URBs myself instead.- If an isochronous transfer URB completes with status==0, also check the
status of the frame descriptors.- Verify length of interrupt messages received from the device.
- Align the length limit on transmitted AT commands with the device
documentation.- In case of AT response receive overrun, keep newly arrived instead of old
unread data.- Remove redundant check of device ID in the USB probe function.
- Correct and improve some comments and formatting.
