From f6d335c08df48b318187a087c9c38ba3d416e115 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 21 May 2010 15:27:09 +0100 Subject: AFS: Don't put struct file on the stack Don't put struct file on the stack as it takes up quite a lot of space and violates lifetime rules for struct file. Rather than calling afs_readpage() indirectly from the directory routines by way of read_mapping_page(), split afs_readpage() to have afs_page_filler() that's given a key instead of a file and call read_cache_page(), specifying the new function directly. Use it in afs_readpages() as well. Also make use of this in afs_mntpt_check_symlink() too for the same reason.
