All error/warnings (new ones prefixed by >>, old ones prefixed by <<):

>> WARNING: modpost: fs/cifsd/ksmbd.o(.init.text+0x1c0): Section mismatch in reference from the function init_module() to the function .exit.text:ksmbd_release_inode_hash()
The function __init init_module() references
a function __exit ksmbd_release_inode_hash().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __exit annotation of
ksmbd_release_inode_hash() so it may be used outside an exit section.
