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 ?
