21 Enables support for file system.
38 int "Maximum number of distinct file system types allowed"
41 Zephyr provides several file system types including FatFS and
50 system types. Zero or a negative value selects the maximum
53 file system. Selecting a value less than the actual length
54 supported by a file system may result in memory access

10 decouples the applications from directly accessing an individual file system's
11 specific API or internal functions by introducing file system registration
14 In Zephyr, any file system implementation or library can be plugged into or
15 pulled out through a file system registration API. Each file system
25 Zephyr RTOS supports multiple instances of a file system by making use of
26 the mount point as the disk volume name, which is used by the file system library
29 A file system is declared as:
41 - ``FS_FATFS`` is the file system type like FATFS or LittleFS.
42 - ``FATFS_MNTP`` is the mount point where the file system will be mounted.
