While writing a version of losetup, I ran into the problem that the loop device was returning total garbage. It turns out the problem was that this losetup was only issuing the LOOP_SET_FD ioctl and not issuing a subsequent LOOP_SET_STATUS ioctl. This losetup didn't have any special status to set, so it left out the call. The deeper cause is that loop_set_fd sets the transfer function to NULL, which causes no transfer to happen lo_do_transfer. This patch fixes the problem by setting transfer to transfer_none in loop_set_fd. Signed-off-by:

Sometimes partitions claim to be larger than the reported capacity of a disk device. This patch makes the kernel warn about those partitions. We still permit these patitions to be used. Quoting Andries Brouwer <Andries.Brouwer@cwi.nl>: Case 1: The kernel is mistaken about the size of the disk. (There are commands to clip a disk to a certain capacity, there are jumpers to tell a disk that it should report a certain capacity etc. Usually this is because of BIOS bugs. In bad cases the machine will crash in the BIOS and hence fail to boot if the disk reports full capacity.) In such cases actually accessing the blocks of the partition may work fine, or may work fine after running an unclip utility. I wrote "setmax" some years ago precisely for this reason. Case 2: There was a messy partition table (maybe just a rounding error) but the actual filesystem on the partition is contained in the physical disk. Now using the filesystem goes without problem. Case 3: Both partition and filesystem extend beyond the end of the disk. In forensic or debugging situations one often uses a copy of the start of a disk. Now access beyond the end gives an expected I/O error. Signed-off-by:

Split the checkpoint list of the transaction into two lists. In the first list we keep the buffers that need to be submitted for IO. In the second list are kept buffers that were already submitted and we just have to wait for the IO to complete. This should simplify a handling of checkpoint lists a bit and can eventually be also a performance gain. Signed-off-by:

When CONFIG_BASE_SAMLL=1, cascade() in may enter the infinite loop. Because of CONFIG_BASE_SMALL=1(TVR_BITS=6 and TVN_BITS=4), the list base->tv5 may cascade into base->tv5. So, the kernel enters the infinite loop in the function cascade().

If invalidate_mapping_pages is called to invalidate a very large mapping (e.g. a very large block device) and if the only active page in that device is near the end (or at least, at a very large index), such as, say, the superblock of an md array, and if that page happens to be locked when invalidate_mapping_pages is called, then pagevec_lookup will return this page and as it is locked, 'next' will be incremented and pagevec_lookup will be called again. and again. and again. while we count from 0 upto a very large number. We should really always set 'next' to 'page->index+1' before going around the loop again, not just if the page isn't locked. Cc: "Steinar H. Gunderson" <sgunderson@bigfoot.com> Signed-off-by:

The percpu counter data type are changed in this set of patches to support more users like ext3 who need more than 32 bit to store the free blocks total in the filesystem. - Generic perpcu counters data type changes. The size of the global counter and local counter were explictly specified using s64 and s32. The global counter is changed from long to s64, while the local counter is changed from long to s32, so we could avoid doing 64 bit update in most cases. - Users of the percpu counters are updated to make use of the new percpu_counter_init() routine now taking an additional parameter to allow users to pass the initial value of the global counter.

- When setting a sighandler using sigaction() call, if the flag SA_ONSTACK is set and no alternate stack is provided via sigaltstack(), the kernel still try to install the alternate stack. This behavior is the opposite of the one which is documented in Single Unix Specifications V3. - Also when setting an alternate stack using sigaltstack() with the flag SS_DISABLE, the kernel try to install the alternate stack on signal delivery. These two use cases makes the process crash at signal delivery. Signed-off-by:

There are a couple of places where JBD has to check to see whether an unneeded memory allocation was performed. Usually it _was_ needed, so we end up calling kfree(NULL).

If you get to that point in the code it means that desc->move_irq is set, pending_irq_cpumask[irq] and cpu_online_map should have a value. Still pretty good chance anding those two you'll still have a value. So these two branch predictors should be inverted. Signed-off-by:
