Detailed Description

Volumes on block devices, mounted into the VFS.

A filesystem implements vfs_fs_ops_t and owns every path below its mount point. Boards list their mounts in the device description, and the generated dt_mount_all() mounts them at startup; each library is compiled only when a board uses it.

Filesystem	Suited to	Mount function
FAT filesystem	Removable media shared with other systems	fs_fat_mount()
littlefs filesystem	Storage the firmware owns; survives resets during writes	fs_littlefs_mount()

Files and storage compares them and describes mounting, path resolution, and descriptors across the whole VFS.
