m0_fi_add_dyn_id()

M0_INTERNAL int m0_fi_add_dyn_id

(

char *

str

)

Add a dynamically allocated fault point ID string to persistent storage, which will be cleaned during m0_fi_fini() execution.

This function aimed to be used together with m0_fi_enable_xxx() functions.

m0_fi_fpoint_type_name()

M0_INTERNAL const char* m0_fi_fpoint_type_name

(

enum m0_fi_fpoint_type

type

)

Returns the name of fault point type

Here is the caller graph for this function:

m0_fi_states_get()

M0_INTERNAL const struct m0_fi_fpoint_state* m0_fi_states_get

(

void

)

A read-only "getter" of global fi_states array, which stores all FP states.

The fi_states array is a private data of lib/finject.c and it should not be modified by external code. This function deliberately returns a const pointer to emphasize this. The main purpose of this function is to provide the FP states information to m0ctl driver, which displays it via debugfs.

Returns

A constant pointer to global fi_states array.

Here is the caller graph for this function:

m0_fi_states_get_free_idx()

M0_INTERNAL uint32_t m0_fi_states_get_free_idx

(

void

)

A read-only "getter" of global fi_states_free_idx index of fi_states array.

Returns

Current value of fi_states_free_idx variable.
