Good morning,
update: this problem still exists on 3.6.2-1-ARCH and it got worse:
I reformatted the external disk to use xfs, but as the my
root filesystem is still jfs, it still appears:
Active / Total Objects (% used): 642732 / 692268 (92.8%)
Active / Total Slabs (% used) : 24801 /
Adding automated test to check event's perf_event_attr values.
The idea is run perf session with kidnapping sys_perf_event_open
function. For each sys_perf_event_open call we store the
perf_event_attr data to the file to be checked later against what
we expect.
You can run this by:

The --sort documentation for top and report was hopelessly out-of-date
Instead of having two more places that would need to be updated,
just point to --help.

Recent Intel CPUs have a new alternative MSR range for perfctrs that allows
writing the full counter width. Enable this range if the hardware reports it
using a new capability bit. This lowers overhead of perf stat slightly because
it has to do less interrupts to accumulate the c

With checkpointed counters there can be a situation where the counter
is overflowing, aborts the transaction, is set back to a non overflowing
checkpoint, causes interupt. The interrupt doesn't see the overflow
because it has been checkpointed. This is then a spurious PMI, typic

When a weighted sample is requested, first try to report the TSX abort cost
on Haswell. If that is not available report the memory latency. This
allows profiling both by abort cost and by memory latencies.
Memory latencies requires enabling a different PEBS mode (LL).

Haswell has two additional LBR from flags for TSX: intx and abort, implemented
as a new v4 version of the LBR format.
Handle those in and adjust the sign extension code to still correctly extend.
The flags are exported similarly in the LBR record to the existing misprediction

When the LBR format is unknown disable LBR recording. This prevents
crashes when the LBR address is misdecoded and mis-sign extended.

Haswell. This allows e.g. to profile the number of cycles in transactions.
The checkpointed qualifier requires forcing the event to

Add histogram support for the transaction flags. Each flags instance becomes
a separate histogram. Support sorting and displaying the flags in report

The patch is fairly large, but it's really mostly just plumbing to pass the
