Task for clone operation.
Multiple task can concurrently work on a clone operation.
uint Clone_Task::m_alloc_len |
Serial descriptor allocated length.
uint Clone_Task::m_buffer_alloc_len |
Allocated buffer length.
byte* Clone_Task::m_current_buffer |
Allocated buffer.
pfs_os_file_t Clone_Task::m_current_file_des |
Current file descriptor.
uint Clone_Task::m_current_file_index |
Current file index.
uint32_t Clone_Task::m_data_size |
Data transferred for current chunk in bytes.
int Clone_Task::m_debug_counter |
Counter to restart in different state.
bool Clone_Task::m_file_cache |
Data files are read using OS buffer cache.
bool Clone_Task::m_has_thd |
