• CI checks

No, this PR does not fully meet the NuttX requirements. While it provides a summary, it lacks crucial details. Here's a breakdown of the missing information:

• Summary: Needs more detail. Why is loading kernel modules from hostfs necessary? What problem does it solve or what functionality does it enable? Which part of the kernel is changed (e.g., module loader, VFS)? How does this change work technically? Are there any related NuttX issues?

• Impact: "None" is highly unlikely. At a minimum, this impacts the build system (since hostfs needs to be enabled), potentially impacts hardware (if hostfs driver is specific), and definitely impacts documentation (this is a new feature and needs to be documented). Security and compatibility implications should also be considered. This section needs thorough review and realistic answers.

• Testing: While local testing is mentioned, the logs are missing. CI checks are insufficient without demonstrating the actual change in behavior. The target configuration (board:config) is vague. More specific information on the target and build host is needed (e.g., "Build Host: Linux (Ubuntu 20.04), x86_64, GCC 9.4.0. Target: qemu-armv7a, sim:nsh"). Critically, the logs showing the module loading from hostfs are absent. Before/after logs should clearly demonstrate the new functionality working.

In short, the PR needs significantly more detail in every section to meet the requirements. The current description is too superficial to allow for proper review.
