Hi,
I had post a simillar message before.
Thanks for the replay from Albert D. Cahalan. But i found some results
confusing me.
For example, process 1 and process 2 run concurrently and execute the
following system calls.
rename("/usr/hybrid/cfg/data","/usr/mytemp/data1"); /*for process 1*/
----------------------------------------------------------------
rename("/usr/mytemp/data1","/usr/test");/* for process 2*/
----------------------------------------------------------------
It is possible that context switch happens when process 1 is look ing up
the inode for "/usr/mytemp/data1" or the inode for "/usr/hybrid/cfg/data".
It will result in diffrent behaviour for process 2 and confuses the
application.
If so,how does Linux solve?
Thanks.
Warren
