Field Documentation

◆ rh_addb2_net

struct m0_addb2_net* rh_addb2_net

Definition at line 147 of file reqh.h.

◆ rh_addb2_net_idle

struct m0_semaphore rh_addb2_net_idle

Definition at line 148 of file reqh.h.

◆ rh_addb2_stor

struct m0_addb2_storage* rh_addb2_stor

Definition at line 145 of file reqh.h.

◆ rh_addb2_stor_idle

struct m0_semaphore rh_addb2_stor_idle

Definition at line 146 of file reqh.h.

◆ rh_beseg

struct m0_be_seg* rh_beseg

BE segment for this request handler.

Definition at line 112 of file reqh.h.

◆ rh_conf_cache_ast

struct m0_sm_ast rh_conf_cache_ast

AST for rconfc cache events to be done asynchronously.

Definition at line 230 of file reqh.h.

◆ rh_conf_cache_exp

struct m0_chan rh_conf_cache_exp

Channel for configuration cache expiry events.

The channel callbacks are to be executed synchronously in the context of the thread where m0_rconfc::rc_expired_cb is called.

The channel callback must not attempt to do synchronous reading on m0_reqh::rh_rconfc::rc_confc.

Definition at line 194 of file reqh.h.

◆ rh_conf_cache_ready

struct m0_chan rh_conf_cache_ready

Channel for configuration cache ready events.

The channel callbacks are to be executed synchronously in the context of the thread where m0_rconfc::rc_ready_cb is called.

The channel callback must not attempt to do synchronous reading on m0_reqh::rh_rconfc::rc_confc.

Definition at line 205 of file reqh.h.

◆ rh_conf_cache_ready_async

struct m0_chan rh_conf_cache_ready_async

Channel for configuration cache ready events.

The channel callbacks are to be executed asynchronously in the context of the locality other than locality0 used by rconfc. The broadcast on the channel is postponed until synchronous part is fully completed.

The channel callback is allowed to do synchronous reading on m0_reqh::rh_rconfc::rc_confc.

Note: : The order of clink subscription matters: m0_pools_common::pc_conf_ready_async should be the last clink to subscribe this channel. Rationale: the subsystems using m0_pool/m0_pool_version/m0_client_layout/ should relinquish their pointers/references for in-memory objects before pools_common's callback is executed. Currently this is achieved by registering pools_common's clinks after registering clinks of all layout users.
