Code tracking when transaction needs to be committed on fdatasync(2) forgets to handle a situation when only inode's i_size is changed. Thus in such situations fdatasync(2) doesn't force transaction with new i_size to disk and that can result in wrong i_size after a crash. Fix the issue by updating inode's i_datasync_tid whenever its size is updated.

Pull LogFS bugfixes from Prasad Joshi: - "logfs: query block device for number of pages to send with bio" This BUG was found when LogFS was used on KVM. The patch fixes the problem by asking for underlaying block device the number of pages to send with each BIO. - "logfs: maintain the ordering of meta-inode destruction" LogFS maintains file system meta-data in special inodes. These inodes are releated to each other, therefore they must be destroyed in a proper order. - "logfs: initialize the number of iovecs in bio" LogFS used to panic when it was created on an encrypted LVM volume. The patch fixes the problem by properly initializing the BIO. Plus a couple more: - logfs: create a pagecache page if it is not present - logfs: destroy the reserved inodes while unmounting * tag 'for-linus' of git://github.com/prasad-joshi/logfs_upstream: logfs: query block device for number of pages to send with bio logfs: maintain the ordering of meta-inode destruction logfs: create a pagecache page if it is not present logfs: initialize the number of iovecs in bio logfs: destroy the reserved inodes while unmounting

For certain speculative events on Power7, 'perf stat' reports far higher event count than 'perf record' for the same event. As described in following commit, a performance monitor exception is raised even when the the performance events are rolled back. commit 0837e324 Author: Anton Blanchard <anton@samba.org> Date: Wed Mar 9 14:38:42 2011 +1100 perf_event_interrupt() records an event only when an overflow occurs. But this check for overflow is a simple 'if (val < 0)'. Because the events are rolled back, this check for overflow fails and the event is not recorded. perf_event_interrupt() later uses pmc_overflow() to detect the overflow and resets the counters and the events are lost completely. To properly detect the overflow of rolled back events, use pmc_overflow() even when recording events. To reproduce: $ cat strcpy.c #include <stdio.h> #include <string.h> main() { char buf[256]; alarm(5); while(1) strcpy(buf, "string1"); } $ perf record -e r20014 ./strcpy $ perf report -n > report.1 $ perf stat -e r20014 > report.2 # Compare report.1 and report.2 Reported-by: Maynard Johnson <mpjohn@us.ibm.com> Signed-off-by: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

For powerpc BooKE and e200, singlestep is handled on the critical/dbg exception stack. This causes current_thread_info() to fail for kgdb internal, so previously We work around this issue by copying the thread_info from the kernel stack before calling kgdb_handle_exception, and copying it back afterwards. But actually we don't do this properly. We should backup current_thread_info then restore that when exit.
