v9fs_client_init() steps over each option with "options += length + 1",
to skip the comma after it. The last option has no comma, so the step
goes past the terminating NUL, and the loop parses the memory after the
string as more options. If that memory has a "trans=" or "uname=", it
replaces the option given.
For example, NSH keeps the next argument after the options:
nsh> mount -t v9fs -o trans=virtio,tag=host trans=x /mnt
nsh: mount: mount failed: 2
The parser reads "trans=x", and there is no transport "x". The same
thing happens to options in .rodata, as CONFIG_INIT_MOUNT_DATA is.
Skip the comma only when there is one.

nxstyle reports "Missing blank line after declarations" in three places.
Add the blank lines, because CI checks every file that a change touches.
No functional change. The change is whitespace only.

Fix some misspelled field names.
These field names seem to be used only in private contexts.
Thus, the probability of external code accessing these fields is very
low.
In the rare case of external usage, compile time errors will easily
direct users to the new field name.
Summary:
There are differences in different server implementations, so it is necessary to check whether the returned nwqid satisfies the requested number.

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

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.
