misc: Fix spelling mistakes

The new open function introduces requirement to provide callback function that will be called by

asynchronous event such as bdev removal. `spdk_bdev_open_ext` function takes bdev name as

an argument instead of bdev structure to avoid a race condition that can happen when the bdev

is being removed between a call to get its structure based on a name and actually openning it.

New 'resize' event has been added to notify about change of block count property of block device.

Event is delivered only if block device was opened with `spdk_bdev_open_ext` function.

Added `spdk_rpc_is_method_allowed` function for checking whether method is permitted in a given state.

Added `spdk_rpc_get_state` to check current state of RPC server.

RPC `wait_subsystem_init` has been added to allow clients to block untill all subsystems are initialized.

### git pre-commit and pre-push hooks

The pre-commit hook will run `scripts/check_format.sh` and verify there are no

formating errors before allowing `git commit` to run. The pre-push hook runs

formatting errors before allowing `git commit` to run. The pre-push hook runs

`make CONFIG_WERROR=y` with and without `CONFIG_DEBUG=y` using both the gcc and

clang compiler before allowing `git push` to run. Following each DEBUG build

`test/unit/unittest.sh` is run and verified. Results are recorded in the

There are several dependencies to leverage the Linux idxd driver for driving DSA devices.

1 Linux kernel support: You need to have a Linux kernel with the `idxd` driver

loaded. Futher, add the following command line options to the kernel boot

loaded. Further, add the following command line options to the kernel boot

commands:

```bash

}

```

To determine the name of available modules and their supported operations use the

RPC `accel_get_module_info`.

After power failure, FTL needs to rebuild the whole L2P using the address maps (`P2L`) stored within each band/chunk.

This needs to done, because while individual L2P pages may have been paged out and persisted to the cache device,

there's no way to tell which, if any, pages were dirty before the power failure occured. The P2L consists of not only

there's no way to tell which, if any, pages were dirty before the power failure occurred. The P2L consists of not only

the mapping itself, but also a sequence id (`seq_id`), which describes the relative age of a given logical block

(multiple writes to the same logical block would produce the same amount of P2L entries, only the last one having the current data).

This will result in errors if these are not available which is very possible if

gdb is used for reasons other than debugging spdk core dumps.
