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_

Summary:
In the x86 environment, memory does not necessarily start at 0, so when end is 0x0, start = end + 1, and then determine the contents of start, it will cause x86 to cause a crash when accessing an illegal address.
This problem does not occur in the arm environment because arm starts at 0x0, so the content of the 0x1 address is “\0”.

Summary:
1.The relpath information is stored in the fid structure
2.The relative path information is only saved in the client. When the server changes, the relpath saved in the fid will not change.
