lguest needs to hold a reference to its task in case it exits while another Guest is sending it I/O. Otherwise we can oops in access_process_vm->get_task_mm->task_lock().

1) Bridging via host is broken: we need to set "promisc" bit in MAC address published by the host so the guest sends us everything. Thanks James Morris for the report (I don't use bridging). 2) Lguest network device uses 0 to mean "noone at this slot". It used to use 0xFF, and one spot was missed. Minor: it just means we'll have a useless extra transmit

Here's couple of patches to improve the softlockup watchdog. The first changes the softlockup timer from using jiffies to sched_clock() as a timebase. Xen and VMI implement sched_clock() as counting unstolen time, so time stolen by the hypervisor won't cause the watchdog to bite. The second adds per-cpu enable flags for the watchdog timer. This allows the timer to be disabled when the

Dear Rusers, I am trying to feed my database with data from a file. But since my file (2010101000.txt) there`s no headers I am facing problem because the result data.frame is not separated my columns. How could I set variables names for each columns in *dbWriteTable*? I have tried the command below but I don`t know how to fill the *field.type*option. dbWriteTable(con, "b20101010",

new_inode() does not return ERR_PTR() but NULL in case of failure. Correct checking of the return value.

While adding a file into orphan dir in ocfs2_orphan_add(), it calls __ocfs2_add_entry() before ocfs2_journal_access_di(). If ocfs2_journal_access_di() failed, the file is added into orphan dir, and orphan dir dinode updated, but file dinode has not been updated. Accordingly, the data is not consistent between file dinode and orphan dir. So, need to call ocfs2_journal_access_di() before

More goo from hrtimers integration. We do compile and run properly with NO_HZ enabled. There was a period when we didn't because of a missing export, but that was since fixed. And with the clocksource code now firmly in place, we can get rid of code that fixes up the wallclock, since this is done in the common infrastructure. This actually fixes a timer bug as well, that was caused by
