Andy Ross 6965cf526d kernel: Deprecate k_mem_pool APIs
Mark all k_mem_pool APIs deprecated for future code.  Remaining
internal usage now uses equivalent "z_mem_pool" symbols instead.

The commit changes error handling by fs_unmount; the function will
return -EINVAL if mount point, described by mp, is not mounted or
-ENNOTSUP when unmounting is not supported by the driver; in the second
case it will also log error.

Additionally to the above changes, checks for correct mnt_path and
mnt_path, within fs_unmount, have been removed as they are not needed;
only the fs_mount_t->fs pointer is needed to decide whether system is

Peter A. Bigot d0d3c4a3a7 fs: allow external file system implementations
The documentation claims that Zephyr supports external file system
implementations, and there's no reason not to do so.  Rework the API
to allow this.

Note that the file system type cannot legally be an enum anymore,
since we need to support file system types that don't have an
identifier assigned in that enum.  Rely on the implicit conversion of
enum values to int to preserve backwards compatibility.

Tobias Svehagen 50ed105d05 fs: nvs: Fix handling of corrupt ate's in garbage collector
nvs_gc does not verify the crc8 of close_ate before using
close_ate.offset.  This means that close_ate.offset could contain an
offset that points beyond valid ate's in the sector. For example, there
might be a valid ate at offset 0x100 but close_ate.offset is 0x200.
If that is the case that value will not be moved and so it will be lost.

Solve this by refactoring the recovery loop from nvs_prev_ate into
nvs_recover_last_ate and use that function in nvs_gc if a corrupt
close_ate is found.

The crc8 of gc_ate is not checked before trying to find another ate
with the same id. If there are no valid ate with that id in the whole
fs the inner while(1)-loop will never stop since the break condition
includes a check for a correct crc8.

Solve this by skipping gc_ate's with an invalid crc8.

Ulf Magnusson 975de21858 kconfig: Global whitespace/consistency cleanup
Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).

Go for the most common style:

 - Indent properties with a single tab, including for choices.

   Properties on choices work exactly the same syntactically as
   properties on symbols, so not sure how the no-indentation thing
   happened.

 - Indent help texts with a tab followed by two spaces

 - Put a space between 'config' and the symbol name, not a tab. This
   also helps when grepping for definitions.

 - Do '# A comment' instead of '#A comment'

I tweaked Kconfiglib a bit to find most of the stuff.

Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

Justin Brzozoski d0a368e2e0 nvs: fix overwriting with truncated data
When overwriting an NVS item with data that was a truncated version of
the existing data, the "is this already saved" logic was ignoring the
differing lengths and not saving the new item because the data matched.

Peter A. Bigot 167eb53e74 subsys/fs/littlefs: allow customization of file system configuration
There's desire to be able to customize parameters on a per-filesystem
basis, which means we need a way to override the Kconfig defaults which
are global.  This also means the littlefs data structure cannot own the
cache and lookahead buffers.

Switch to using a macro to define the littlefs data structure.  The
default version uses the Kconfig constants.  A custom one takes
arguments providing the most likely partition-specific parameters.
Finally the user is free to bypass the helper macros and set any
parameters desired, though validation is limited and only present when
CONFIG_DEBUG is enabled.

Extend the test suite with a performance module, which confirms that
these settings have an impact proportional to the log of changes to the
cache or IO sizes.

Peter A. Bigot 312f05eaef subsys/fs: add implementation helper module
File system API functions that operate on paths are passed both the
absolute path including the mount point prefix, and the mount point
within which the path lies.

Unfortunately it's not entirely trivial to convert an arbitrary path
within the file system space to an absolute path within its mount point,
because the path may be to the mount point itself and not end with a
directory separator.  The effect is that a file system implementation
like nffs may be given an empty path when "/" is required.

Add an implementation module that does this transformation and use it to
transform paths within each filesystem wrapper.
