.. option:: CONFIG_FS_LITTLEFS_FC_MEM_POOL_NUM_BLOCKS

*Number of maximum sized blocks in littlefs file cache heap (DEPRECATED)*

Type: ``int``

Help
====

A heap for file cache data is sized so that
FS_LITTLEFS_FC_MEM_POOL_NUM_BLOCKS allocations of size
FS_LITTLEFS_MEM_POOL_MAX_SIZE can be active simultaneously.

This option configures the total heap size based on the
block size.

This API is no longer approprate as the underlying storage solution
has been deprecated.  Instead use FS_LITTLEFS_FC_HEAP to configure
the size of a heap used to allocate caches for open files.
