deep chmod|chown -R begin to start OOMkiller

[CHIKAMA masaki <masaki-c@xxxxxxxxxx>]

Hello all.

I have trouble about a storange behavior on xfs fileststem.
When I did "chmod -R 755 ." on deep directory, the system became 
slow down and began to start OOMkiller after a while.

At that time, slabtop showed that the number of xfs_ili, xfs_inode, 
and linvfs_icache objects are becoming very large.

My kernel version is 2.6.13.4. 

A similar report is found at
 http://oss.sgi.com/archives/linux-xfs/2003-03/msg00018.html


Is this a expected bihavior?


Now I use "find -exec" insted of "chmod -R".
The usage of slab memory with "find" is calm and does not start
OOM killker.
