Detailed Description

struct nilfs_sc_info - Segment constructor information : Back pointer to super_block struct : root object of the current filesystem tree : Block count of current generation : List of files to be written : List of GC inodes having blocks to be written : array of segment numbers to be freed : number of segments on : inode whose data pages are written for a sync operation : start byte offset of data pages : end byte offset of data pages (inclusive) : List of segment buffers : List of segment buffers to hold logs under writing : Number of available blocks in segment buffers. : Current segment buffer : Collection stage : pointer to the current finfo struct in the segment summary : pointer to the current binfo struct in the segment summary : Block count of a file : Data block count of a file : Number of blocks included in the current logical segment : Creation time : checkpoint number of current log : Internal flags : spinlock for sc_state and so on : Segctord state flags : inode bitmap of metadata files to be flushed : Client request queue : Daemon wait queue : Start/end wait queue to control segctord task : Request counter : Accepted request count : Completion counter : Request of explicit sync operation : Timeout value of background construction : Frequency of creating checkpoints : Start time of the latest logical segment : Watermark for the number of dirty buffers : Timer for segctord : current thread of segctord
