Thanks... I've applied your patch to 4.19-rc2 and run it through xfstests.
It is in my linux-next tree now.
I put that in there because I'm really just an old system administrator,
and I would always be happy when I could tail dmesg and see some
hint at why something wasn't doing as I expected.

With the range check it is possible to do a quick verification that the
current mapping is correct vs. the static protection areas.
In case a incorrect mapping is detected a warning is emitted and the large
page is split up. If the large page is a 2M page, then the split code is
forced to check
Avoid the extra variable and gotos by splitting the function into the
actual algorithm and a callable function which contains the lock
protection.
Rename it to should_split_large_page() while at it so the return values make
actually sense.
Clean up the code flow, comments and general whitespace
When the existing mapping is correct and the new requested page protections
are the same as the existing ones, then further checks can be omitted and the
large page can be preserved. The slow path 4k wise check will not come up with
a different result.
Before:
1G pages checked:
The large page preservation mechanism is just magic and provides no
information at all. Add optional statistic output in debugfs so the magic can
be evaluated. Defaults is off.
Output:
1G pages checked:2
1G pages sameprot: 0
1G pages preserved:
The whole static protection magic is silently fixing up anything which is
handed in. That's just wrong. The offending call sites need to be fixed.
Add a debug mechanism which emits a warning if a requested mapping needs to be
fixed up. The DETECT debug mechanism is really not meant to be enabled
To avoid excessive 4k wise checks in the common case do a quick check first
whether the requested new page protections conflict with a static
protection area in the large page. If there is no conflict then the
decision whether to preserve or to split the page can be made immediately.
If the
The extra loop which tries hard to preserve large pages in case of conflicts
with static protection regions turns out to be not preserving anything, at
least not in the experiments which have been conducted.
There might be corner cases in which the code would be able to preserve a
large page
static_protections() is pretty unreadable. Split it up into separate checks
for each protection area.

Checking static protections only page by page is slow especially for huge
pages. To allow quick checks over a complete range, add the ability to do
that.
Make the checks inclusive so the ranges can be directly used for debug output
later.
No functional change.

Bin reported that try_preserve_large_page() in the page attribute code
consumes an large amount of CPU time. His initial attempts of addressing
this made me look deeper into the code.

completely irrelevant.

Hi Linus,
Just one small fix here, preventing a VM_WARN_ON when a !present PMD/PUD

Correct. My patch fixes both issues.

Nice.

This patch adds the various helper functions needed for authentication
support. We need functions to hash nodes, to embed HMACs into a node and
to compare hashes and HMACs. Most functions first check if this
filesystem is authenticated and bail out early if not, which makes the
functions safe to
During creation of the default filesystem on an empty flash the default
LPT is created. With this patch a hash over the default LPT is
calculated which can be added to the default filesystems master node.

Nodes that are written to flash can only be authenticated through the
index after the next commit. When a journal replay is necessary the
nodes are not yet referenced by the index and thus can't be
authenticated.
This patch overcomes this situation by creating a hash over all nodes
beginning from
In authenticated mode we cannot fixup the inode sizes in-place
during recovery as this would invalidate the hashes and HMACs
we stored for this inode.
Instead, we just write the updated inodes to the journal. We can
only do this after ubifs_rcvry_gc_commit() is done though, so for
authenticated
The master node contains hashes over the root index node and the LPT.
This patch adds a HMAC to authenticate the master node itself.

As part of the UBIFS authentication support every branch in the index
gets a hash covering the referenced node. To make that happen the tree
node cache needs hashes over the nodes. This patch adds a hash argument
to ubifs_tnc_add() and ubifs_tnc_add_nm(). The hashes are calculated
from the callers

The superblock node is read/modified/written several times throughout
the UBIFS code. Instead of reading it from the device each time just
keep a copy in memory and write back the modified copy when necessary.
This patch helps for authentication support, here we not only have to
read the
The LPT needs to be authenticated aswell. Since the LPT is only written
during commit it is enough to authenticate the whole LPT with a single
hash which is stored in the master node. Only the leaf nodes (pnodes)
are hashed which makes the implementation much simpler than it would be
to hash the
