In nfs v3 ,if mulity process visit nfs mount nfs dir ,there sometimes occour .nfsXXX can't delete .

If modify sillyrename to put files in /tmp ,it will be more friendly to nfs user.


the background
   1¡¢Linux fs has   /nfsmnt/work_pub/web and /nfsmnt/work_inwork/web £¬they use NFS V3 mount
   2¡¢there is many process will read and write files in the dir /nfsmnt/work_pub/web 
   3¡¢cron will del  all files in dir  /nfsmnt/work_pub/web in period£¬and will copy all the files which in the dir /nfsmnt/work_inwork/web 

in some times delete all files in  /nfsmnt/work_pub/web will faild ,because there is some .nfsXXXX



My question is :can i modify nfs_sillyrename funncion  in the fs/nfs/dir.c , general all .nfsXXX in /tmp,and make kernel ?

No it wouldn't. Think permissions....

What would then happen if /tmp was on a separate filesystem than the
original file?

Then modify the cron job to ignore ".nfs*" files.
