Name:tracing_err_log_open

Proto:static int tracing_err_log_open(struct inode *inode, struct file *file)

Type:int

Parameter:

TypeParameterName
struct inode *inode
struct file *file
7244  tr = s or device private pointer
7245  ret = 0
7247  ret = tracing_check_open_get_tr(tr)
7248  If ret Then Return ret
7252  If f_mode & le is open for writing && f_flags & O_TRUNC Then clear_tracing_err_log(tr)
7255  If f_mode & le is open for reading Then
7256  ret = seq_open(file, & tracing_err_log_seq_ops)
7257  If Not ret Then
7258  m = needed for tty driver, and maybe others
7259  private = tr
7260  Else
7261  race_array_put - Decrement the reference counter for this trace array.* NOTE: Use this when we no longer need the trace array returned by* trace_array_get_by_name(). This ensures the trace array can be later* destroyed.
