The truncate_inode_page call in ocfs_file_release causes the severethroughput drop of file reading in OCFS2.
Hi,
We have investigated the possible causes of the severe
throughput drop of file reading in OCFS2 that found in the iozone
benchmark. We find the major cause is the inadequate inode page cache
cleaning when open or close the last reference to an inode.
In routine ocfs_file_release(), if the caller is the last
reference to this inode, truncate_inode_page is called to invalidate all
page
