2009-01-06wusb: return -ENOTCONN when resetting a port with no connected deviceDavid Vrabel2-0/+4
If reading the device descriptor fails during hub_port_init() fails, then the port is disabled, disconnecting the device. The port is then reset at the start of the next init attempt but there is no device to reset. Signed-off-by: David Vrabel <david.vrabel@csr.com>
2009-01-06uwb: safely remove all reservationsDavid Vrabel1-4/+13

Pull structures that bridge the gap between snapshot and exception store out of dm-snap.h and put them in a new .h file - dm-exception-store.h. This file will define the API for new exception stores.

Use scheduled_work() for the asynchronous uevents instead. Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2009-01-06dm: add name and uuid to sysfsMilan Broz4-2/+136
Implement simple read-only sysfs entry for device-mapper block device. This patch adds a simple sysfs directory named "dm" under block device properties and implements - name attribute (string containing mapped device name) - uuid attribute (string containing UUID, or empty string if not set) The kobject is embedded in mapped_device struct, so no additional memory allocation is needed for initializing sysfs entry. During the processing of sysfs attribute we need to lock mapped device which is done by a new function dm_get_from_kobj, which returns the md associated with kobject and increases the usage count. Each 'show attribute' function is responsible for its own locking. Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2009-01-06dm table: rework reference countingMikulas Patocka4-20/+33
Rework table reference counting. The existing code uses a reference counter. When the last reference is dropped and the counter reaches zero, the table destructor is called. Table reference counters are acquired/released from upcalls from other kernel code (dm_any_congested, dm_merge_bvec, dm_unplug_all). If the reference counter reaches zero in one of the upcalls, the table destructor is called from almost random kernel code. This leads to various problems: * dm_any_congested being called under a spinlock, which calls the destructor, which calls some sleeping function. * the destructor attempting to take a lock that is already taken by the same process. * stale reference from some other kernel code keeps the table constructed, which keeps some devices open, even after successful return from "dmsetup remove". This can confuse lvm and prevent closing of underlying devices or reusing device minor numbers. The patch changes reference counting so that the table destructor can be called only at predetermined places. The table has always exactly one reference from either mapped_device->map or hash_cell->new_map. After this patch, this reference is not counted in table->holders. A pair of dm_create_table/dm_destroy_table functions is used for table creation/destruction. Temporary references from the other code increase table->holders. A pair of dm_table_get/dm_table_put functions is used to manipulate it. When the table is about to be destroyed, we wait for table->holders to reach 0. Then, we call the table destructor. We use active waiting with msleep(1), because the situation happens rarely (to one user in 5 years) and removing the device isn't performance-critical task: the user doesn't care if it takes one tick more or not. This way, the destructor is called only at specific points (dm_table_destroy function) and the above problems associated with lazy destruction can't happen. Finally remove the temporary protection added to dm_any_congested(). Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2009-01-06dm: support barriers on simple devicesAndi Kleen4-10/+26
Implement barrier support for single device DM devices This patch implements barrier support in DM for the common case of dm linear just remapping a single underlying device. In this case we can safely pass the barrier through because there can be no reordering between devices. NB. Any DM device might cease to support barriers if it gets reconfigured so code must continue to allow for a possible -EOPNOTSUPP on every barrier bio submitted. - agk Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>

2009-01-06dm log: avoid reinitialising io_req on every operationTakahiro Yasui1-10/+7
rw_header function updates three members of io_req data every time when I/O is processed. bi_rw and notify.fn are never modified once they get initialized, and so they can be set in advance. header_to_disk() can also be pulled out of write_header() since only one caller needs it and write_header() can be replaced by rw_header() directly.

2009-01-06dm: consolidate target deregistration error handlingMikulas Patocka9-48/+16
Change dm_unregister_target to return void and use BUG() for error reporting. dm_unregister_target can only fail because of programming bug in the target driver. It can't fail because of user's behavior or disk errors. This patch changes unregister_target to return void and use BUG if someone tries to unregister non-registered target or unregister target that is in use. This patch removes code duplication (testing of error codes in all dm targets) and reports bugs in just one place, in dm_unregister_target. In some target drivers, these return codes were ignored, which could lead to a situation where bugs could be missed.

2009-01-06dm raid1: fix error countJonathan Brassow1-3/+3
Always increase the error count when I/O on a leg of a mirror fails. The error count is used to decide whether to select an alternative mirror leg. If the target doesn't use the "handle_errors" feature, the error count is not updated and the bio can get requeued forever by the read callback. Fix it by increasing error_count before the handle_errors feature checking.

2009-01-05net/ehea: bitops work on unsigned longsStephen Rothwell2-3/+2
The flags field of struct ehea_port is only used with test_bit(), clear_bit() and set_bit() and these interfaces only work on "unsigned long"s, so change the field to be an "unsigned long". Also, this field only has two bits defined for it (0 and 1) so will still be fine if someone builds this driver for a 32 bit arch (at least as far as this flags field is concerned). Also note that ehea_driver_flags is only used in ehca_main.c, so make it static in there. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-05add a vfs_fsync helperChristoph Hellwig1-17/+1
Fsync currently has a fdatawrite/fdatawait pair around the method call, and a mutex_lock/unlock of the inode mutex. All callers of fsync have to duplicate this, but we have a few and most of them don't quite get it right. This patch adds a new vfs_fsync that takes care of this. It's a little more complicated as usual as ->fsync might get a NULL file pointer and just a dentry from nfsd, but otherwise gets afile and we want to take the mapping and file operations from it when it is there. Notes on the fsync callers: - ecryptfs wasn't calling filemap_fdatawrite / filemap_fdatawait on the lower file - coda wasn't calling filemap_fdatawrite / filemap_fdatawait on the host file, and returning 0 when ->fsync was missing - shm wasn't calling either filemap_fdatawrite / filemap_fdatawait nor taking i_mutex. Now given that shared memory doesn't have disk backing not doing anything in fsync seems fine and I left it out of the vfs_fsync conversion for now, but in that case we might just not pass it through to the lower file at all but just call the no-op simple_sync_file directly. [and now actually export vfs_fsync] Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2009-01-04qeth: avoid crash in case of layer mismatch for VSWITCHUrsula Braun3-6/+14
For z/VM GuestLAN or VSWITCH devices the transport layer is configured in z/VM. The layer2 attribute of a participating Linux device has to match the z/VM definition. In case of a mismatch Linux currently crashes in qeth recovery due to a reference to the not yet existing net_device. Solution: add a check for existence of net_device and add a message pointing to the mismatch of layer definitions in Linux and z/VM.
