ocfs2: replace zero-length arrays with DECLARE_FLEX_ARRAY() helper
Zero-length arrays are deprecated and we are moving towards adopting C99 flexible-array members, instead. So, replace zero-length array declarations in a couple of structures and unions with the new DECLARE_FLEX_ARRAY() helper macro.
This helper allows for a flexible-array member in a union and as only member in a structure.
Also, this addresses multiple warnings reported when building with Clang-15 and -Wzero-length-array.
Lastly, this will also help memcpy (in a coming hardening update) execute proper bounds-checking on variable length object i_symlink at fs/ocfs2/namei.c:1973:
fs/ocfs2/namei.c: 1973 memcpy((char *) fe->id2.i_symlink, symname, l);

treewide: remove editor modelines and cruft
The section "19) Editor modelines and other cruft" in Documentation/process/coding-style.rst clearly says, "Do not include any of these in source files."
I recently receive a patch to explicitly add a new one.
Let's do treewide cleanups, otherwise some people follow the existing code and attempt to upstream their favoriate editor setups.
It is even nicer if scripts/checkpatch.pl can check it.
If we like to impose coding style in an editor-independent manner, I think editorconfig (patch [1]) is a saner solution.

ocfs2: fix value of OCFS2_INVALID_SLOT
In the ocfs2 disk layout, slot number is 16 bits, but in ocfs2 implementation, slot number is 32 bits. Usually this will not cause any issue, because slot number is converted from u16 to u32, but OCFS2_INVALID_SLOT was defined as -1, when an invalid slot number from disk was obtained, its value was (u16)-1, and it was converted to u32. Then the following checking in get_local_system_inode will be always skipped:
static struct inode **get_local_system_inode(struct ocfs2_super *osb, int type, u32 slot) { BUG_ON(slot == OCFS2_INVALID_SLOT); ... }

ocfs2: ocfs2_fs.h: replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99:
struct foo { int stuff; struct boo array[]; };
By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by this change:
"Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

ocfs2: make append_dio an incompat feature
It turns out that making this feature ro_compat isn't quite enough to prevent accidental corruption on mount from older kernels. Ocfs2 (like other file systems) will process orphaned inodes even when the user mounts in 'ro' mode. So for the case of a filesystem not knowing the append_dio feature, mounting the filesystem could result in orphaned-for-dio files being deleted, which we clearly don't want.
So instead, turn this into an incompat flag.
Btw, this is kind of my fault - initially I asked that we add a flag to cover the feature and even suggested that we use an ro flag. It wasn't until I was looking through our commits for v4.0-rc1 that I realized we actually want this to be incompat.

This patch also adds stackflags to sb->s_clusterinfo. It also introduces a clusterinfo flag OCFS2_CLUSTER_O2CB_GLOBAL_HEARTBEAT to denote the enabled global heartbeat mode.
This incompat flag can be set/cleared using tunefs.ocfs2 --fs-features. The clusterinfo flag is set/cleared using tunefs.ocfs2 --update-cluster-stack.

ocfs2: Cache system inodes of other slots.
Durring orphan scan, if we are slot 0, and we are replaying orphan_dir:0001, the general process is that for every file in this dir: 1. we will iget orphan_dir:0001, since there is no inode for it. we will have to create an inode and read it from the disk. 2. do the normal work, such as delete_inode and remove it from the dir if it is allowed. 3. call iput orphan_dir:0001 when we are done. In this case, since we have no dcache for this inode, i_count will reach 0, and VFS will have to call clear_inode and in ocfs2_clear_inode we will checkpoint the inode which will let ocfs2_cmt and journald begin to work. 4. We loop back to 1 for the next file.
So you see, actually for every deleted file, we have to read the orphan dir from the disk and checkpoint the journal. It is very time consuming and cause a lot of journal checkpoint I/O. A better solution is that we can have another reference for these inodes in ocfs2_super. So if there is no other race among nodes(which will let dlmglue to checkpoint the inode), for step 3, clear_inode won't be called and for step 1, we may only need to read the inode for the 1st time. This is a big win for us.
So this patch will try to cache system inodes of other slots so that we will have one more reference for these inodes and avoid the extra inode read and journal checkpoint.

ocfs2: increase the default size of local alloc windows
I have observed that the current size of 8M gives us pretty poor fragmentation on multi-threaded workloads which do lots of writes.
Generally, I can increase the size of local alloc windows and observe a marked decrease in fragmentation, even up and beyond window sizes of 512 megabytes. This makes sense for a couple reasons - larger local alloc means more room for reservation windows. On multi-node workloads the larger local alloc helps as well because we don't have to do window slides as often.
Also, I removed the OCFS2_DEFAULT_LOCAL_ALLOC_SIZE constant as it is no longer used and the comment above it was out of date.
To test fragmentation, I used a workload which launched 4 threads that did 4k writes into a series of about 140 alternating files.
With resv_level=2, and a 4k/4k file system I observed the following average fragmentation for various localalloc= parameters:
localalloc= avg. fragmentation 8 48 32 16 64 10 120 7
On larger cluster sizes, the difference is more dramatic.
The new default size top out at 256M, which we'll only get for cluster sizes of 32K and above.
