- If enabled, the following functions are provided by the VFS component.
- open, close, read, write, pread, pwrite, lseek, fstat, fsync, ioctl, fcntl
- Filesystem drivers can then be registered to handle these functions
- for specific paths.
- Disabling this option can save memory when the support for these functions
- is not required.

- # is not a big overhead, compared to code size of the filesystem,
- # so make this depend on IO.

- If enabled, select function is provided by the VFS component, and can be used
- on peripheral file descriptors (such as UART) and sockets at the same time.
- If disabled, the default select implementation will be provided by LWIP for
- sockets only.
- Disabling this option can reduce code size if support for "select" on UART file
- descriptors is not required.

- bool "Suppress select() related debug outputs"
- depends on VFS_SUPPORT_SELECT
- default y
- help
- Select() related functions might produce an unconveniently lot of
- debug outputs when one sets the default log level to DEBUG or higher.
- It is possible to suppress these debug outputs by enabling this
- option.
