This is not a good concept at all , why linux is wasting precious RAM unnecassarily, if not required .
Then what will happen for Embedded system (like in my case), which do not have any Hard disk , only things they have Flash or Ram.

If i create and delete files with same name , inode_cache & dentry_cache increases only one time , there is no problem . If i create and delete files with different name , inode_cache & dentry_cache increases continously and will eat my whole RAM and crash system.
And if i create and delete my file after long lapse , inode_cache & dentry_cache are restore after some time , their is no problem . But if i create and delete files very frequently , inode_cache & dentry_cache get no time for restore and eat my whole RAM and crash system.
If i donot create and delete files files frequently with different name , their is no problem at all.

Thank you very much for your suggestions , i was getting this problem in my ARM target machine and right now i am working on SH target machines , and i am quite busy with my SH target machines now , i have to do lot of setups to change my target machines , i am sorry right now i am not in position to test your suggestions , but as soon as my SH target machine work is over , i will test all your suggestions and options.
BTW, i am getting Ramdisk intialization problem in SH target machine.
Thank you,
