96206cbf9d fs/xxfs:Replace kmm with fs heap 
Summary:
  1.Add configuration to allocate memory from the specified section
  2.Replace all memory operations (kmm_) in the vfs with
    fs_heap_. When FS_HEAPSIZE > 0, memory is requested for the file system by specifying a configured heap location. By default (i.e. FS_HEAPSIZE=0) fs_heap_ is equivalent to kmm_

4cec713dbf fs_inode:Change the type of i_crefs to atomic_int 
Summary:
  1.Modified the i_crefs from int16_t to atomic_int
  2.Modified the i_crefs add, delete, read, and initialize interfaces to atomic operations
The purpose of this change is to avoid deadlock in cross-core scenarios, where A Core blocks B Core’s request for a write operation to A Core when A Core requests a read operation to B Core.

14602be4cc fs/lock: Limit inode type for file locks 
When we close a socket fd, it will call get path on sockets.
`close(socket_fd)` -> `file_closelk(filep)` -> `file_fcntl(F_GETPATH)`
It causes a heavy stack load for each socket close operation.
(We have `GETPATH` for sockets to be used for `fdinfo`)

But the socket fds are not intended to be used for file locks.
And so do some other file types, so we may just limit the usage of flock.
