If the caller tries to instantiate a directory using an inode that already has a dentry alias, then we attempt to rename the existing dentry instead of instantiating a new one. Fail with an ELOOP error if the rename would affect one of our parent directories. This behaviour is needed in order to avoid issues such as http://bugzilla.kernel.org/show_bug.cgi?id=7178Signed-off-by:

CCISS was producing warnings about shifts being greater than the size of the type and pointers being of incompatible type. Turns out this is because it's calling do_div on a 32-bit quantity. Upon further investigation, the sector_t total_size is being assigned to an int, and then we're calling do_div on that int. Obviously, sector_div is called for here, and I took the chance to refactor the code a little. Signed-off-by:

Mistyped an ifdef CONFIG_CPUSETS - fixed. I doubt that anyone ever noticed. The impact of this typo was that if someone: 1) was using MPOL_BIND to force off node allocations 2) while using cpusets to constrain memory placement 3) when that cpuset was migrating that jobs memory 4) while the tasks in that job were actively forking then there was a rare chance that future allocations using that MPOL_BIND policy would be node local, not off node.

The zonelist may contain zones of nodes that have not been bootstrapped and we will oops if we try to allocate from those zones. So check if the node information for the slab and the node have been setup before attempting an allocation. If it has not been setup then skip that zone. Usually we will not encounter this situation since the slab bootstrap code avoids falling back before we have setup the respective nodes but we seem to have a special needs for pppc. Signed-off-by:

The recent commit 751ae21c introduced a bug in the producer/consumer index calculation in the ibmveth driver - incautious use of the post-increment ++ operator resulted in an increment being immediately reverted. This patch corrects the logic. Without this patch, the driver oopses almost immediately after activation on at least some machines. Signed-off-by:

I have an acpi_pm that goes backwards, but it's not intel. I tested the verified read and my acpi_pm started to function properly. So I added it to the greylist. I'm assuming that's the right spot. I also added an unlikely() to the while, cause it seems appropriate. Signed-off-by:

The change from __setup() to module_param_named() requires users to prefix the option with "generic.". This patch re-adds the __setup() additionally to the module_param_named(). Usually it would make sense getting rid of such an obsolete __setup() at some time, but considering that drivers/ide/ is slowly approaching a RIP status it's already implicitely scheduled for removal. This patch fixes kernel Bugzilla #7353. Signed-off-by:

Commits 881a8c12 and efe1ec27 corrects pci device matching in only one way; it no longer oopses/crashes, despite hotplug is not solved in these changes. Whenever pci_find_device -> pci_get_device change is performed, also pci_dev_get and pci_dev_put should be in most cases called to properly handle hotplug. This patch does exactly this thing -- increase refcount to let kernel know, that we are using this piece of HW just now. It affects moxa and rio char drivers. Cc: <R.E.Wolff@BitWizard.nl> Acked-by:

This reverts commit 4596c75c as requested by Olaf Hering. It causes compile errors, and says Olaf: "This change is also wrong, the autoloading works perfect with 2.6.18, no need to add random PCI ids. See commit a0245f7a, platform devices have now a modalias entry in sysfs. The network card is not a PCI device." Signed-off-by:

NeilBrown authored
This patch is suitable for just about any 2.6 kernel. It should go in 2.6.19 and 2.6.18.2 and possible even the .17 and .16 stable series. This is a long standing bug that seems to have only recently become apparent, presumably due to increasing use of NFS over TCP - many distros seem to be making it the default. The SK_CONN bit gets set when a listening socket may be ready for an accept, just as SK_DATA is set when data may be available. It is entirely possible for svc_tcp_accept to be called with neither of these set. It doesn't happen often but there is a small race in svc_sock_enqueue as SK_CONN and SK_DATA are tested outside the spin_lock. They could be cleared immediately after the test and before the lock is gained. This normally shouldn't be a problem. The sockets are non-blocking so trying to read() or accept() when ther is nothing to do is not a problem. However: svc_tcp_recvfrom makes the decision "Should I accept() or should I read()" based on whether SK_CONN is set or not. This usually works but is not safe. The decision should be based on whether it is a TCP_LISTEN socket or a TCP_CONNECTED socket. Signed-off-by:

A disk generated some I/O error, after it, I hitted J_ASSERT(transaction->t_updates > 0) in journal_stop(). It seems to happened on ext3_truncate() path from stack trace. Then, maybe the following case may trigger J_ASSERT(transaction->t_updates > 0). ext3_truncate() -> ext3_free_branches() -> ext3_journal_test_restart() -> ext3_journal_restart() -> journal_restart() transaction->t_updates--; /* another process aborted journal */ -> start_this_handle() returns -EROFS without transaction->t_updates++; -> ext3_journal_stop() -> journal_stop() J_ASSERT(transaction->t_updates > 0) If journal was aborted in middle of journal_restart(), ext3_truncate() may trigger J_ASSERT().
