If a snapshot became invalid while there are outstanding pending_exceptions, when pending_complete() processes each one it forgets to remove the corresponding exception from its exception table before freeing it. Fix this by moving the 'out:' label up one statement so that remove_exception() is always called. Then __invalidate_exception() no longer needs to call it and its 'pe' argument become superfluous.

Add a workqueue so that I/O can be queued up to be flushed from a separate thread (e.g. if local interrupts are disabled). A new per-snapshot spinlock pe_lock is introduced to protect queued_bios. Signed-off-by:

This patch rearranges the pending_complete() code so that the functional changes in subsequent patches are clearer. By consolidating the error and the non-error paths, we can move error_snapshot_bios() and __flush_bios() in line. Signed-off-by:

This patch rearranges the snapshot_map code so that the functional changes in subsequent patches are clearer. The only functional change is to replace the existing read lock with a write lock which the next patch needs. Signed-off-by:

When suspending a device-mapper device, dm_suspend() sleeps until all necessary I/O is completed. This state is triggered by a callback from persistent_commit(). But some I/O can still be issued *after* the callback (to prepare the next metadata area for use if the current one is full). This patch delays the callback until after that I/O is complete.

read_exception() and write_exception() only return an error if supplied with an out-of-range index. If this ever happens it's the result of a bug in the calling code so we handle this with an assertion and remove the error handling in the callers. Signed-off-by:

Fix the error handling when store.read_metadata is called: the error should be returned immediately. Signed-off-by:

The chunk size of snapshots cannot be changed so it is redundant to require it as a parameter when activating an existing snapshot. Allow a value of zero in this case and ignore it. For a new snapshot, use a default value if zero is specified. Signed-off-by:

While reading the code I found a bug in the error path in alloc_dev in dm.c When blk_alloc_queue fails there is no call to free_minor. This patch fixes the problem. Signed-off-by:

The new ioctl code passes the wrong file pointer to the underlying device. No file pointer is available so make a temporary fake one. ioctl_by_bdev() does set_fs(KERNEL_DS) so it's for ioctls originating within the kernel and unsuitable here. We are processing ioctls that originated in userspace and mapping them to different devices. Fixing the existing callers that pass a NULL file struct and consolidating the fake_file users are separate matters to solve in later patches. Signed-off-by:

Export blkdev_driver_ioctl for device-mapper. If we get as far as the device-mapper ioctl handler, we know the ioctl is not a standard block layer BLK* one, so we don't need to check for them a second time and can call blkdev_driver_ioctl() directly. Signed-off-by:

When an ioctl is performed on a multipath device simply pass it on to the underlying block device through current_path. If current path is not yet selected, select it. Signed-off-by:

When an ioctl is performed on a device with a linear target, simply pass it on to the underlying block device. Note that the ioctl will pass through the filtering in blkdev_ioctl() twice. Signed-off-by:

Milan Broz authored
Extend the core device-mapper infrastructure to accept arbitrary ioctls on a mapped device provided that it has exactly one target and it is capable of supporting ioctls. [We can't use unlocked_ioctl because we need 'inode': 'file' might be NULL. Is it worth changing this?] Signed-off-by:

xmon writes garbage on the screen because the nvidia console driver has changed the line pitch from what the firmware set it to. Fix it by making the nvidia driver inform the btext engine (which xmon uses if the screen is its output device) about changes to display resolution. Signed-off-by:

This patch fixes a bug where we obtain a smaller resolution than requested. (eg: in 640x480, only 639x479 usable pixels). This was due to 1 being substracted from the xres and yres vars two times: first in mbxfb.c and then in the macros from reg_bits.h. This patch removes the minus ones from the mbxfb.c file. Tested and works. Signed-off-by:

This is a workaround for what I think is a bug in the 2700G chip. The PLL output frequency is adustable using 3 values (M, N and P. See code for formula). The N value range is documented to be 1 to 7 but when it is set to 1, the output frequency is lower than it should be (divided by 2), giving unexpected results such as no sync on a CRT display. This patch prevents N=1 when searching for the best value for the requested pixclock. Signed-off-by:
