For a reason that I was unable to understand in three months of debugging,
mount ext2 -o remount stopped working properly when remounting from
regular operation to xip, or the other way around. According to a git
bisect search, the problem was introduced with the VM_MIXEDMAP/PTE_SPECIAL
rework in the vm:
commit 70688e4dd1
Author: Nick Piggin <npiggin@suse.de>
Date: Mon Apr 28 02:13:02 2008 -0700
xip: support non-struct page backed memory
In the failing scenario, the filesystem is mounted read only via root=
kernel parameter on s390x. During remount (in rc.sysinit), the inodes of
the bash binary and its libraries are busy and cannot be invalidated (the
bash which is running rc.sysinit resides on subject filesystem).
Afterwards, another bash process (running ifup-eth) recurses into a
subshell, runs dup_mm (via fork). Some of the mappings in this bash
process were created from inodes that could not be invalidated during
remount.
Both parent and child process crash some time later due to inconsistencies
in their address spaces. The issue seems to be timing sensitive, various
attempts to recreate it have failed.
This patch refuses to change the xip flag during remount in case some
inodes cannot be invalidated. This patch keeps users from running into
that issue.

I enabled all cgroup subsystems when compiling kernel, and then:
# mount -t cgroup -o net_cls xxx /mnt
# mkdir /mnt/0
This showed up immediately:
BUG: MAX_LOCKDEP_SUBCLASSES too low!
turning off the locking correctness validator.
It's caused by the cgroup hierarchy lock:
for (i = 0; i < CGROUP_SUBSYS_COUNT; i++) {
struct cgroup_subsys *ss = subsys[i];
if (ss->root == root)
mutex_lock_nested(&ss->hierarchy_mutex, i);
}
Now we have 9 cgroup subsystems, and the above 'i' for net_cls is 8, but
MAX_LOCKDEP_SUBCLASSES is 8.
This patch uses different lockdep keys for different subsystems.

Fix kernel-doc processing of SYSCALL wrappers.
The SYSCALL wrapper patches played havoc with kernel-doc for
syscalls. Syscalls that were scanned for DocBook processing
reported warnings like this one, for sys_tgkill:
Warning(kernel/signal.c:2285): No description found for parameter 'tgkill'
Warning(kernel/signal.c:2285): No description found for parameter 'pid_t'
Warning(kernel/signal.c:2285): No description found for parameter 'int'
because the macro parameters all "look like" function parameters,
although they are not:
/**
* sys_tgkill - send signal to one specific thread
* @tgid: the thread group ID of the thread
* @pid: the PID of the thread
* @sig: signal to be sent
*
* This syscall also checks the @tgid and returns -ESRCH even if the PID
* exists but it's not belonging to the target process anymore. This
* method solves the problem of threads exiting and PIDs getting reused.

When I tested following program, I found that the mlocked counter
is strange. It cannot free some mlocked pages.
It is because try_to_unmap_file() doesn't check real
page mappings in vmas.
That is because the goal of an address_space for a file is to find all
processes into which the file's specific interval is mapped. It is
related to the file's interval, not to pages.
Even if the page isn't really mapped by the vma, it returns SWAP_MLOCK
since the vma has VM_LOCKED, then calls try_to_mlock_page. After this the
mlocked counter is increased again.
COWed anon page in a file-backed vma could be a such case. This patch
resolves it.

This reverts commit c87591b719.
Since journal_start_commit() is now fixed to return 1 when we started a
transaction commit, there's some transaction waiting to be committed or
there's a transaction already committing, we don't need to call
ext3_force_commit() in ext3_sync_fs(). Furthermore ext3_force_commit()
can unnecessarily create sync transaction which is expensive so it's
worthwhile to remove it when we can.

journal_start_commit() returns 1 if either a transaction is committing or
the function has queued a transaction commit. But it returns 0 if we
raced with somebody queueing the transaction commit as well. This
resulted in ext3_sync_fs() not functioning correctly (description from
Arthur Jones): In the case of a data=ordered umount with pending long
symlinks which are delayed due to a long list of other I/O on the backing
block device, this causes the buffer associated with the long symlinks to
not be moved to the inode dirty list in the second phase of fsync_super.
Then, before they can be dirtied again, kjournald exits, seeing the UMOUNT
flag and the dirty pages are never written to the backing block device,
causing long symlink corruption and exposing new or previously freed block
data to userspace.
This can be reproduced with a script created by Eric Sandeen
<sandeen@redhat.com>:
#!/bin/bash
umount /mnt/test2
mount /dev/sdb4 /mnt/test2
rm -f /mnt/test2/*
dd if=/dev/zero of=/mnt/test2/bigfile bs=1M count=512

Commit 5a6fe12595 brought hugetlbfs more
in line with the core VM by obeying VM_NORESERVE and not reserving
hugepages for both shared and private mappings when [SHM|MAP]_NORESERVE
are specified. However, it is still taking filesystem quota
unconditionally.
At fault time, if there are no reserves and attempt is made to allocate
the page and account for filesystem quota. If either fail, the fault
fails. The impact is that quota is getting accounted for twice. This
patch partially reverts 5a6fe12595. To
help prevent this mistake happening again, it improves the documentation
of hugetlb_reserve_pages()

Here we do two things:
First, revert "iwlwifi: save PCI state before suspend, restore after
resume". That misguided patch led to being unable to use iwlwifi
devices after resume.
Next, indicate to PCI driver that the saved PCI state is valid during suspend.
We restore PCI state and enable the device when network interface is created,
similarly PCI state is saved and the device is disabled when network interface
is removed. Thus, when .suspend is called the PCI state is saved and device
is disabled. This is the case even if an interface is never created as PCI
state is saved and device disabled during .probe.
PCI driver assumes PCI state is saved in .suspend. Saving the state at this
time will save state of disabled device and thus cause problems during
resume (resuming a disabled device). We thus indicate directly to PCI
driver that current PCI saved state is valid.

I noticed by pure accident we have ptrace_fork() and friends. This was
added by "x86, bts: add fork and exit handling", commit

I can't test this, ds_request_bts() returns -EOPNOTSUPP, but I strongly
believe this needs the fix. I think something like this program
int main(void)
{
int pid = fork();
if (!pid) {
ptrace(PTRACE_TRACEME, 0, NULL, NULL);
kill(getpid(), SIGSTOP);
fork();
} else {
struct ptrace_bts_config bts = {
.flags = PTRACE_BTS_O_ALLOC,
.size = 4 * 4096,
};
wait(NULL);
ptrace(PTRACE_SETOPTIONS, pid, NULL, PTRACE_O_TRACEFORK);
ptrace(PTRACE_BTS_CONFIG, pid, &bts, sizeof(bts));
ptrace(PTRACE_CONT, pid, NULL, NULL);
sleep(1);
}
return 0;
}
should crash the kernel.
If the task is traced by its natural parent ptrace_reparented() returns 0
but we should clear ->btsxxx anyway.

Currently, the sunhme driver installs SBus Quattro interrupt handler
when at least one HME card was initialized correctly and at least one
Quattro card is present. This breaks when a Quattro card fails
initialization for whatever reason - IRQ is registered and OOPS happens
when it fires.
The solution, as suggested by David Miller, was to keep track which
cards of the Quattro bundles have been initialized, and request/free the
Quattro IRQ only when all four devices have been successfully
initialized.
The patch only touches SBus initialization - PCI init already resets the
card pointer to NULL on init failure.
The patch has been tested on Sun E3500 with SBus and PCI single HME
cards and one PCI Quattro HME card in a situation where any PCI card
failed init when the SBus routines tried to init them by mistake.
Additionally it replaces Quattro request_irq panic with error return -
if this card fails to work, at least let the others work.
Tested on E450 with PCI HME and PCI Quad HME.
