TRIG_ROUND_NEAREST is 0, so a bit-and with it is always false. The value TRIG_ROUND_MASK covers the bits of the TRIG_ROUND constants, so first pick those bits and then make the test using ==. The same is done for TRIG_ROUND_UP for symmetry, even though bit-and would be sufficient in this case. This problem was found using Coccinelle (http://coccinelle.lip6.fr/). Signed-off-by:

This code is used by some combination of the CONFIG_COMEDI_DAS08_CS, CONFIG_COMEDI_DAS08_ISA, and CONFIG_COMEDI_DAS08_PCI and contains a lot of conditional compilation. Remove most of the conditional compilation, relying on the compiler to optimize out unused static functions and data. Use the '__maybe_unused' tag for those functions that cause compiler warnings as a result of this. Also change the DO_COMEDI_DRIVER_REGISTER macro from a conditionally defined macro to a manifest constant macro to allow it to be tested outside the preprocessor (although this is not currently needed).

Commit f80a3f62 ("Staging: strip: delete the driver") left if_strip.h unused: nothing in the tree includes it anymore. It is still exported, but since nothing in the kernel uses struct MetricomAddress, that seems pointless. Delete this header too. Signed-off-by:

xvmalloc can't handle PAGE_SIZE page so that zram have to handle it specially but zsmalloc can do it so let's remove unnecessary special handling code. Quote from Nitin "I think page vs handle distinction was added since xvmalloc could not handle full page allocation. Now that zsmalloc allows full page allocation, we can just use it for both cases. This would also allow removing the ZRAM_UNCOMPRESSED flag. The only downside will be slightly slower code path for full page allocation but this event is anyways supposed to be rare, so should be fine." 1. This patch reduces code very much. drivers/staging/zram/zram_drv.c | 104 +++++-------------------------------- drivers/staging/zram/zram_drv.h | 17 +----- drivers/staging/zram/zram_sysfs.c | 6 +-- 3 files changed, 15 insertions(+), 112 deletions(-) 2. change pages_expand with bad_compress so it can count bad compression(above 75%) ratio. 3. remove zobj_header which is for back-reference for defragmentation because firstly, it's not used at the moment and zsmalloc can't handle bigger size than PAGE_SIZE so zram can't do it any more without redesign.

fd1a30de makes a bug that it uses (struct page *) as zsmalloc's handle although it's a uncompressed page so that it can access random page, return random data or even crashed by get_first_page in zs_map_object.

We should use unsigned long as handle instead of void * to avoid any confusion. Without this, users may just treat zs_malloc return value as a pointer and try to deference it. This patch passed compile test(zram, zcache and ramster) and zram is tested on qemu. changelog * from v2 - remove hval pointed out by Nitin - based on next-20120607 * from v1 - change zcache's zv_create return value - baesd on next-20120604 Cc: Dan Magenheimer <dan.magenheimer@oracle.com> Acked-by:

These two places seem like they should be using bitwise OR instead of bitwise AND. The first one is a noop which is equivalent to: imr |= (0x0100 & 0x0004 & 0x0001); The second is sets lcr2 to zero instead of just clearing the high bits. lcr2 &= (0x00F0 & 0x000F); Signed-off-by:

Use scnprint instead of snprintf, because snprintf returns the number of bytes that would have been written to the buffer if there was enough space, and as a result writing to buf[len-1] might cause a access beyond the buffers limits. Reported-by:

When uninstalling a device, there is a loop of calls that produces, at the end, two calls to __ipoctal_remove() function with the same ipack_device argument. The first time works fine, but the second will fail in tty_unregister_driver() To avoid this situation, the call to __ipoctal_remove() it is done only from the ipack bus driver and not from the ipack device driver.

When a bus driver calls ipack_driver_register(), it should manages the returning NULL value to undo all the operations it did before this call, and print the corresponding trace. It is not a task for the ipack driver to call the remove() function here. Signed-off-by:
