2006-06-23[PATCH] VFS: Permit filesystem to override root dentry on mountDavid Howells1-3/+3
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.

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.

And: Tilman Schmidt <tilman@imap.cc> The following patches add drivers for the Siemens Gigaset 3070 family of ISDN DECT PABXes connected via USB, either directly or over a DECT link using a Gigaset M105 or compatible DECT data adapter. The devices are integrated as ISDN adapters within the isdn4linux framework, supporting incoming and outgoing voice and data connections, and also as tty devices providing access to device specific AT commands. Supported devices include models 3070, 3075, 4170, 4175, SX205, SX255, and SX353 from the Siemens Gigaset product family, as well as the technically identical models 45isdn and 721X from the Deutsche Telekom Sinus series. Supported DECT adapters are the Gigaset M105 data and the technically identical Gigaset USB Adapter DECT, Sinus 45 data 2, and Sinus 721 data (but not the Gigaset M34 and Sinus 702 data which advertise themselves as CDC-ACM devices). These drivers have been developed over the last four years within the SourceForge project http://sourceforge.net/projects/gigaset307x/. They are being used successfully in several installations for dial-in Internet access and for voice call switching with Asterisk. This is our second attempt at submitting these drivers, taking into account the comments we received to our first submission on 2005-12-11. The patch set adds three kernel modules: - a common module "gigaset" encapsulating the common logic for controlling the PABX and the interfaces to userspace and the isdn4linux subsystem. - a connection-specific module "bas_gigaset" which handles communication with the PABX over a direct USB connection. - a connection-specific module "usb_gigaset" which does the same for a DECT connection using the Gigaset M105 USB DECT adapter. We also have a module "ser_gigaset" which supports the Gigaset M101 RS232 DECT adapter, but we didn't judge it fit for inclusion in the kernel, as it does direct programming of a i8250 serial port. It should probably be rewritten as a serial line discipline but so far we lack the neccessary knowledge about writing a line discipline for that. The drivers have been working with kernel releases 2.2 and 2.4 as well as 2.6, and although we took efforts to remove the compatibility code for this submission, it probably still shows in places. Please make allowances. This patch: Prepare the kernel build infrastructure for addition of the Gigaset ISDN drivers. It creates a Makefile and Kconfig file for the Gigaset driver and hooks them into those of the isdn4linux subsystem. It also adds a MAINTAINERS entry for the driver. This patch depends on patches 2 to 9 of the present set, as without the actual source files, activating the options added here will cause the kernel build to fail.

2006-03-25[PATCH] hysdn: remove custom typesAndrew Morton12-126/+127
hysdn defines its own types: ulong, uint, uchar and word. Problem is, the module_param macros rely upon some of those identifiers having special meanings too. The net effect is that module_param() and friends cannot be used in ISDN because of this namespace clash. So remove the hysdn-private defines and open-code them all.
