Matthew suggest to change linked list of tree connect list to xarray.
It will be tree connect lookup in O(log(n)) time instead of O(n) time.

The error handling in ksmbd_server_init() uses "one function to free
everything style" which is impossible to audit and leads to several
canonical bugs. When we free something that wasn't allocated it may be
uninitialized, an error pointer, freed in a different function or we
try freeing "foo->bar" when "foo" is a NULL pointer. And since the
code is impossible to audit then it leads to memory leaks.
In the ksmbd_server_init() function, every goto will lead to a crash
because we have not allocated the work queue but we call
ksmbd_workqueue_destroy() which tries to flush a NULL work queue.
Another bug is if ksmbd_init_buffer_pools() fails then it leads to a
double free because we free "work_cache" twice. A third type of bug is
that we forgot to call ksmbd_release_inode_hash() so that is a resource
leak.
A better way to write error handling is for every function to clean up
after itself and never leave things partially allocated. Then we can
use "free the last successfully allocated resource" style. That way
when someone is reading the code they can just track the last resource
in their head and verify that the goto matches what they expect.
In this patch I modified ksmbd_ipc_init() to clean up after itself and
then I converted ksmbd_server_init() to use gotos to clean up.

Commit b9d79e4ca4ff ("fbmem: Mark proc_fb_seq_ops as __maybe_unused")
places the '__maybe_unused' in an entirely incorrect location between
the "struct" keyword and the structure name.
It's a wonder that gcc accepts that silently, but clang quite reasonably
warns about it:

Pull scheduler fixes from Thomas Gleixner:
"A set of scheduler updates:
- Prevent PSI state corruption when schedule() races with cgroup
move.
A recent commit combined two PSI callbacks to reduce the number of
cgroup tree updates, but missed that schedule() can drop rq::lock
for load balancing, which opens the race window for
cgroup_move_task() which then observes half updated state.
The fix is to solely use task::ps_flags instead of looking at the
potentially mismatching scheduler state
- Prevent an out-of-bounds access in uclamp caused bu a rounding
division which can lead to an off-by-one error exceeding the
buckets array size.
- Prevent unfairness caused by missing load decay when a task is
attached to a cfs runqueue.

removed. Fix it by enforcing the load update through the hierarchy
