Here is the caller graph for this function:

work_init()

static void work_init ( proto_detail_file_thread_t *  thread, bool  triggered_by_delete  )

static

Start processing a new work file.

Parameters

[in]	thread	the thread instance.
[in]	triggered_by_delete	true if this was triggered by a vnode_delete. When a new file is moved over a workfile vnode delete can serve as an indication that new data is available. It can also mean however, that the file has just been deleted, so we shouldn't treat this failure to open the new file as a fatal error.
