3f47fd767a 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.
