hi all i hav some questions i m reading a book on UNIX-kernals by Mouris j. Bach but i m not sure abt these concepts

does kernal uses the inode(internaly) for rename a file? or as inode don't hav any field related to name of file..rename does changes in only parent directory containt?

does "chmod" command internally opens the file by open function or just changes the inode containt without opening the file?

incore inode no and inode no on the disk are same?

does any file hav more than one incore-inode nos..in any case?

superblock manupulation i.e. allocation of inode nos..buffres to perticular files works always works in Critical Section..?

i know these questions might b funny n so simple for all u Kernal-gurus... but i really wants my concepts clear

thanks and regards deepak thinks.....deeply!
