12 years agoGFS2: Wipe directory hash table metadata when deallocating a directory
Steven Whitehouse [Sat, 21 May 2011 13:05:58 +0000 (14:05 +0100)]
GFS2: Wipe directory hash table metadata when deallocating a directory

The deallocation code for directories in GFS2 is largely divided into
two parts. The first part deallocates any directory leaf blocks and
marks the directory as being a regular file when that is complete. The
second stage was identical to deallocating regular files.

Regular files have their data blocks in a different
address space to directories, and thus what would have been normal data
blocks in a regular file (the hash table in a GFS2 directory) were
deallocated correctly. However, a reference to these blocks was left in the
journal (assuming of course that some previous activity had resulted in
those blocks being in the journal or ail list).

This patch uses the i_depth as a test of whether the inode is an
exhash directory (we cannot test the inode type as that has already
been changed to a regular file at this stage in deallocation)

The original issue was reported by Chris Hertel as an issue he encountered
running bonnie++

Steven Rostedt [Fri, 20 May 2011 17:36:58 +0000 (13:36 -0400)]
ktest: Create variables for the ktest config files

I found that I constantly reuse information for each test case.
It would be nice to just define a variable to reuse.

For example I may have:

TEST_START
[...]
TEST = ssh root@mybox /path/to/my/script

TEST_START
[...]
TEST = ssh root@mybox /path/to/my/script

[etc]

The issue is, I may wont to change that script or one of the other
fields. Then I need to update each line individually.

With the addition of config variables (variables only used during parsing
the config) we can simplify the config files. These variables can
also be defined multiple times and each time the new value will
overwrite the old value.

The convention to use a config variable over a ktest option is to use :=
instead of =.

Now we could do:

USER := root
TARGET := mybox
TEST_SCRIPT := /path/to/my/script
TEST_CASE := ${USER}@${TARGET} ${TEST_SCRIPT}

TEST_START
[...]
TEST = ${TEST_CASE}

TEST_START
[...]
TEST = ${TEST_CASE}

[etc]

Now we just need to update the variables at the top.

powerpc/kvm: Fix kvmppc_core_pending_dec

The vcpu->arch.pending_exceptions field is a bitfield indexed by
interrupt priority number as returned by kvmppc_book3s_vec2irqprio.
However, kvmppc_core_pending_dec was using an interrupt vector shifted
by 7 as the bit index.  Fix it to use the irqprio value for the
decrementer interrupt instead.  This problem was found by code
inspection.

selinux: de-crapify avc cache stat code generation

You can turn off the avc cache stats, but distributions seem to not do
that (perhaps because several performance tuning how-to's talk about the
avc cache statistics).

Which is sad, because the code it generates is truly horrendous, with
the statistics update being sandwitched between get_cpu/put_cpu which in
turn causes preemption disables etc.  We're talking ten+ instructions
just to increment a per-cpu variable in some pretty hot code.

Fix the craziness by just using 'this_cpu_inc()' instead.  Suddenly we
only need a single 'inc' instruction to increment the statistics.  This
is quite noticeable in the incredibly hot avc_has_perm_noaudit()
function (which triggers all the statistics by virtue of doing an
avc_lookup() call).

signal.h need a definition of struct task_struct

This fixes these build errors on powerpc:

  In file included from arch/powerpc/mm/fault.c:18:
  include/linux/signal.h:239: error: 'struct task_struct' declared inside parameter list
  include/linux/signal.h:239: error: its scope is only this definition or declaration, which is probably not what you want
  include/linux/signal.h:240: error: 'struct task_struct' declared inside parameter list
  ..

Exposed by commit e66eed651fd1 ("list: remove prefetching from regular
list iterators"), which removed the include of <linux/prefetch.h> from
<linux/list.h>.

Without that, linux/signal.h no longer accidentally got the declaration
of 'struct task_struct'.

Fix by properly declaring the struct, rather than introducing any new
header file dependency.
