Bug ID: 20132
Summary: on rawhide, struct inode has changed
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: runtime
Assignee: systemtap at sourceware dot org
Reporter: dsmith at redhat dot com
Target Milestone: ---
On rawhide (4.7.0-0.rc0.git5.1.fc25.x86_64), the kernel's 'struct inode' has
changed so that 'i_mutex' no longer exists. Starting with the following commit,
a set of wrapper functions has been added in preparation for the removal of
switching that mutex to a rwsem.
====
commit 5955102c9984fa081b2d570cfac75c97eecf8f3b
Author: Al Viro <viro@zeniv.linux.org.uk>
Date: Fri Jan 22 15:40:57 2016 -0500
wrappers for ->i_mutex access
parallel to mutex_{lock,unlock,trylock,is_locked,lock_nested},
inode_foo(inode) being mutex_foo(&inode->i_mutex).
Please, use those for access to ->i_mutex; over the coming cycle
->i_mutex will become rwsem, with ->lookup() done with it held
only shared.
====
The runtime should be updated to handle this change.
