The inode eviction should unmap the pages associated with the inode. These pages should also be flushed to disk to avoid the data loss. Therefore, use truncate_setsize() in evict_inode() to release the pagecache. The API truncate_setsize() was added in 2.6.35 kernel. To ensure compatibility with the old kernel, the patch defines its own truncate_setsize function. Signed-off-by: Prasad Joshi <pjoshi@stec-inc.com> Closes #255
