Name:ad_seqcount_begin - begin a seq-read critical section*@s: pointer to seqcount_t* Returns: count to be passed to read_seqcount_retry* read_seqcount_begin opens a read critical section of the given seqcount
Proto:static inline unsigned read_seqcount_begin(const seqcount_t *s)
Type:unsigned
Parameter:
| Type | Parameter | Name |
|---|---|---|
| const seqcount_t * | s |
| Name | Describe |
|---|---|
| fprop_fraction_single | Return fraction of events of type pl |
| fprop_fraction_percpu | |
| get_recent_times | |
| ktime_get_real_ts64 | ktime_get_real_ts64 - Returns the time of day in a timespec64.*@ts: pointer to the timespec to be set* Returns the time of day in a timespec64 (WARN if suspended). |
| ktime_get | |
| ktime_get_resolution_ns | |
| ktime_get_with_offset | |
| ktime_get_coarse_with_offset | |
| ktime_mono_to_any | ktime_mono_to_any() - convert mononotic time to any other time*@tmono: time to convert.*@offs: which offset to use |
| ktime_get_raw | ktime_get_raw - Returns the raw monotonic time in ktime_t format |
| ktime_get_ts64 | ktime_get_ts64 - get the monotonic clock in timespec64 format*@ts: pointer to timespec variable* The function calculates the monotonic clock from the realtime* clock and the wall_to_monotonic offset and stores the result |
| ktime_get_real_seconds | ktime_get_real_seconds - Get the seconds portion of CLOCK_REALTIME* Returns the wall clock seconds since 1970. This replaces the* get_seconds() interface which is not y2038 safe on 32bit systems. |
| ktime_get_snapshot | ktime_get_snapshot - snapshots the realtime/monotonic raw clocks with counter*@systime_snapshot: pointer to struct receiving the system time snapshot |
| get_device_system_crosststamp | get_device_system_crosststamp - Synchronously capture system/device timestamp*@get_time_fn: Callback to get simultaneous device time and* system counter from the device driver*@ctx: Context passed to get_time_fn()*@history_begin: Historical reference |
| ktime_get_raw_ts64 | ktime_get_raw_ts64 - Returns the raw monotonic time in a timespec*@ts: pointer to the timespec64 to be set* Returns the raw monotonic time (completely un-modified by ntp) |
| timekeeping_valid_for_hres | mekeeping_valid_for_hres - Check if timekeeping is suitable for hres |
| timekeeping_max_deferment | mekeeping_max_deferment - Returns max time the clocksource can be deferred |
| ktime_get_coarse_real_ts64 | |
| ktime_get_coarse_ts64 | |
| ktime_get_update_offsets_now | ktime_get_update_offsets_now - hrtimer helper*@cwsseq: pointer to check and store the clock was set sequence number*@offs_real: pointer to storage for monotonic -> realtime offset*@offs_boot: pointer to storage for monotonic -> boottime offset*@offs_tai: |
| ioc_now | ake a snapshot of the current [v]time and vrate |
| set_root | |
| __follow_mount_rcu | Try to skip to top of mountpoint pile in rcuwalk mode. Fail if* we meet a managed dentry that would need blocking. |
| follow_dotdot_rcu | |
| path_init | must be paired with terminate_walk() |
| get_fs_root_rcu | |
| get_fs_root_and_pwd_rcu | |
| wake_userfault | |
| read_seqbegin | Read side functions for starting and finalizing a read side section. |
