This patch adds support for the ultrasonic ranger srf04 of devantech. This device is measuring the distance of objects in a range between 1 cm and 3 meters and a theoretical resolution of 3 mm. There are two GPIOs used: - trigger: set as output to the device when the measurement should start - echo: set by the device when the ultrasonic wave is sent out and reset when the echo is recognized; this needs to be an interrupt input The time between setting and resetting the echo pin is the time the waveform needed for one round trip. This time is recorded in the interrupt handler. The distance is calculated in the read function by using the ultrasonic speed at 20 degrees celsius which is about 343 m/s.

The reason for __REQ_LAYOUT_USER__ was to expose a section of code in layout.c to userland for a utility similar to wireshark. This was done before wireshark existed but now that it does we no longer need to do this type of hack. This also reduces lustre_acl.h to strictly a kernel header now. Signed-off-by:

The use of 64 bit time introduces an expensive 64 bit division operation. Since the time lapse being calculated in osc_cache_too_much will never be more than seventy years we can cast the time lapse to an long and perform a normal 32 bit divison operation instead. Signed-off-by:

If an application attempts to remove millions of files in a single directory it will fail. This failure was tracked down to the nlink < 2 check in lmv_revalidate_slaves, because after nlink reaches to maximum value of LDISKFS_LINK_MAX (65000), the nlink broadcast back from the server will be reported as one. The return value of 1 is not invalid so lets remove the check. Signed-off-by:

This patch makes no functional changes. Struct initializers in the fid directory that use C89 or GCC-only syntax are updated to C99 syntax. The C99 syntax prevents incorrect initialization if values are accidently placed in the wrong position, allows changes in the struct definition, and clears any members that are not given an explicit value. The following struct initializers have been updated: lustre/fid/fid_lib.c: const struct lu_seq_range LUSTRE_SEQ_SPACE_RANGE const struct lu_seq_range LUSTRE_SEQ_ZERO_RANGE lustre/fid/lproc_fid.c: struct lprocfs_vars seq_client_debugfs_list Signed-off-by:Steve Guminski <stephenx.guminski@intel.com> Intel-bug-id: https://jira.hpdd.intel.com/browse/LU-6210 Reviewed-on: https://review.whamcloud.com/23789Reviewed-by:

The replay cursor should be updated properly when close happened during replay, otherwise, ptlrpc_replay_next() could run into a dead loop due to an invalid replay cursor: - replay cursor is moved to an open request during replay; - application close that open file, so the rq_replay of the open request is cleared; - ptlrpc_replay_next() calls ptlrpc_free_committed() to free committed/closed requests, the open request is removed from the committed list, so the replay cursor is changed to an empty list_head now. The open request won't be freed now since it's still held by the pending close request; - ptlrpc_replay_next() continue to move the replay cursor to next and run into a dead loop at the end; Another change in this patch is to remove the out of date comments in ptlrpc_replay_next() and cover the whole process of finding replay request within imp_lock, because: 1. With two separated replay lists and replay cursor introduced, finding replay request won't take much time as before, it's not necessary to do this "lock -> unlock -> lock -> unlock" trick anymore; 2. Nowadays there are various kind of non-replay requests are allowed during recovery, so ptlrpc_free_committed() may run in parallel to remove an open request while ptlrpc_replay_next() is iterating the open requests list; Signed-off-by:

ksocklnd reaper thread always tries to close the connection for the first timedout zero-copy TX. This is wrong if this connection is already being closed, because the reaper will see the same TX again and again and cannot find out other timedout zero-copy TXs and close connections for them.

The patch updates the prototype in osc_internal.h to match the enums used in the declaration. The osc_match_base declaration in lustre/osc/osc_request.c uses enums for stricter checking on the type and mode parameters: int osc_match_base(struct obd_export *exp, ... --> enum ldlm_type type, union ldlm_policy_data *policy, --> enum ldlm_mode mode, ... int unref) The prototype in lustre/osc/osc_internal.h instead used unsigned ints: int osc_match_base(struct obd_export *exp, ... --> __u32 type, union ldlm_policy_data *policy, --> __u32 mode, ... int unref); Signed-off-by: -

reply_out_callback() should call ptlrpc_schedule_difficult_reply() to finalize the rs if it's already not on uncommitted list, otherwise, the rs and the export held by rs could be leaked: - target_send_reply() sends a difficult reply before the transaction committed, the reply is linked to scp_rep_active; - export gets disconnected by umount or whatever reason, server_disconnect_export() is called to complete all outstanding replies, which will calls into ptlrpc_handle_rs() to dispose of the rs, so the rs is removed from the uncommitted list and LNetMDUnlink() is called to unlink the reply buffer and generate an unlink event; - reply_out_callback() is called to process above unlink event, ptlrpc_schedule_difficult_reply() is supposed to be called to dispose of the rs finally. However, it could be skipped because of following flawed code snippet: if (!rs->rs_no_ack || rs->rs_transno <= rs->rs_export->exp_obd->obd_last_committed) ptlrpc_schedule_difficult_reply(rs); The intention of above code is: if rs_no_ack is true (COS enabled), and transaction is not committed, we should rely on commit callback to release the rs. However, it overlooked the situation that rs could have been removed from the uncommitted list by disconnecting export. Signed-off-by: -
