(I assume this issue == orphaned inode issue). ext* doesn't have this issue. If ext* made orphaned inode, ext* doesn't delete inode from inode table until calling iput() from last referencer. In FAT case, FAT inode is embedded into dir entry. So, if unlinked inode (then orphaned inode is detached (fat_detach())), FAT deletes inode (dir entry) from dir. -- OGAWA Hirofumi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
