"force" mount option) if it detects that the HFS+ volume has a journal. The code was unconditionally assuming that the volume had a jounal if the journal attribute was set in the volume header. However, the volume also has to have a non-zero journal info block to actually have a journal. In this patch, I refactored the journal detection into a function since the logic is used twice. The journal detection also uses the better logic to determine if there is a journal.

whether a volume has a journal or not. The code currently mounts an HFS+ volume read-only by default when a journal is detected. One can force a read/write mount by giving the "force" mount option. The current code has this behavior since there is no support for the HFS+ journal. My problem is that the detection of the journal could be better. The current code tests the attribute bit in the volume header that indicates there is a journal. If that bit is set, the code assumes that there is a journal. Unfortunately, this is not enough to really determine if there is a journal or not. When that bit is set, one must also examine the journal info block field of the volume header. If this field is 0, there is no journal, and the volume can be mounted read/write. This patch: The HFS+ support in the kernel currently will mount an HFS+ volume read-only if the volume header has the attribute bit set that indicates there is a journal. The kernel does this because there is no support for a journalled HFS+ volume. The problem is that this is only half of what needs to be checked to see if there really is a journal. There is also an entry in the volume header that tells you where to find the journal info block. In the kernel version of the kernel, this 4 byte block is labeled reserved. This patch identifies the journal info block in the header.

However, if an LVDS display is attached (like in laptop) the active pipe variable is never set. The default value is PIPE_A and can be wrong. Set up the pipe variable during driver initialization after hardware state was read. Also, the detection of the active display (and hence the pipe) is wrong. The pipes are assigned to so called planes. Both pipes are always enabled on my laptop but only one plane is enabled (the plane A for the CRT or the plane B for the LVDS). Change active pipe detection code to take into account a status of the plane assigned to each pipe. The problem is visible in the 8 bpp mode if colors above 15 are used. The first 16 color entries are displayed correctly.

i2c_client or spi_device) isn't wakeup capable. For I2C devices there is I2C_CLIENT_WAKE flag exists that we can pass via board info, and if set, I2C core will initialize wakeup capability. For SPI devices there is no such flag at all. I believe that it's not platform code responsibility to allow or disallow wakeups, instead, drivers themselves should set the capability if a device can trigger wakeups. That's what drivers/base/power/sysfs.c says: * It is the responsibility of device drivers to enable (or disable) * wakeup signaling as part of changing device power states, respecting * the policy choices provided through the driver model. I2C and SPI RTC devices send wakeup events via interrupt lines, so we should set the wakeup capability if IRQ is routed. Ideally we should also check irq for wakeup capability before setting device's capability, i.e. if (can_irq_wake(irq)) device_set_wakeup_capable(&client->dev, 1); But there is no can_irq_wake() call exist, and it is not that trivial to implement it for all interrupts controllers and complex/cascaded setups. drivers/base/power/sysfs.c also covers these cases: * Devices may not be able to generate wakeup events from all power * states. Also, the events may be ignored in some configurations; * for example, they might need help from other devices that aren't * active So there is no guarantee that wakeup will actually work, and so I think there is no point in being pedantic wrt checking IRQ wakeup capability.

->d_revalidate() in some cases, but not all cases, and not necessarily by us. Because we need to release the mutex when we call back to the daemon to do perform a mount we must be sure that it is us who holds the mutex so we must redirect mount requests to ->lookup() if the mutex is held.

to send mount requests to ->lookup(). But then we can not rely on d_unhased() to give reliable results because it may be called at any time by any code path. The d_unhashed() function is used by __simple_empty() in the path walking callbacks but autofs mount point dentrys should have no directories at all so a list_empty() on d_subdirs should be (and is) sufficient.

address as *tx_dma = xfer->tx_dma + xfer->len - BUFFER_SIZE; which is constant; i.e. we just send the last BUFFER_SIZE data over again until we've reached the right number of bytes. This patch gets around this by using the /requested/ length when calculating addresses. Note there's no way len != *plen when we calculate the rx buffer address but conceptually we should be using *plen and I don't want someone to come through later, see the calculations for rx and tx are different and "clean up" back to what we had.
