Hi, all the function ext2_find_shared is located fs/ext2/inode.c 935 I see ext2_find_shared is related with truncation, but i don't know what's the use of it. And i am also confused with the implementation of ext2_find_shared. It would be greatly appreciated if somebody can show me what's the use of ext2_find_shared and how it works.
