3ac63edd18 kernel & KernelSU: Deprecated add_try_umount cli, AUTO_ADD_SUS_KSU_DEFAULT_MOUNT and AUTO_ADD_SUS_BIND_MOUNT 
Reason:
 - add_try_umount, AUTO_ADD_SUS_KSU_DEFAULT_MOUNT and AUTO_ADD_SUS_BIND_MOUNT are only used to flag the sus_mount bit on target inode, but actually none of the hooks are checking for this bit, so this is why these features should be no longer needed, and we only need to check for sus mnt_id to determine if it is a sus mount. Plus it takes more CPU cycle to check for the path and set the sus_mount flag during boot time

aa51ef5c24 kernel: kpm: add compatibility for kernel 6.11 and later (#599) 
`cb_mutex` has been removed since this commit(https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/include/linux/netlink.h?h=v6.11&id=5fbf57a937f418fe204f9dbb7735e91984f4ee6a) in 6.11. For compatibility reasons, `cb_mutex` should not be used in 6.11 and later versions.

02c3f70ab5 kernel: expose umount list to ioctl interface (#2950) 
This idea is borrowed from simonpunk's susfs4ksu.
What we see here is that, yeah well, lets just have userspace send us
what it
wants unmounted, this is better than hardcoding everything.

This also solves that issue where MNT_DETACH fails, as long as we send
unmountables in proper order.

A small anti-duplicate mechanism is also added.

While in-kernel umount is a bit worse than zygisk-provider-based ones,
this can still
serve as a healthy alternative.

---------

- Remove duplicate checks

* Remove wrong compatibility code from susfs-main (#596)

Nongki compatibility code should be committed to nongki branch, rather than susfs-main branch.

c61d6fb665 kernel: file_wrapper: copy mode of original inode 
Bionic uses fstat to determine whether an fd is a tty and set proper
buffering flags, so we also need to set the wrapper file's inode mode to
the original inode mode.

see:

1b2e7dee97 kernel: Use task work to install fd
