struct jbd2_inode — The jbd_inode type is the structure linking inodes in ordered mode present in a transaction so that we can sync them during commit.
struct jbd2_inode { transaction_t * i_transaction; transaction_t * i_next_transaction; struct list_head i_list; struct inode * i_vfs_inode; unsigned long i_flags; };
Which transaction does this inode belong to? Either the running transaction or the committing one. [j_list_lock]
Pointer to the running transaction modifying inode's data in case there is already a committing transaction touching it. [j_list_lock]
List of inodes in the i_transaction [j_list_lock]
VFS inode this inode belongs to [constant for lifetime of structure]
Flags of inode [j_list_lock]
