[PATCH v21 036/100] c/r: introduce vfs_fcntl()
This patch introduces vfs_fcntl() so that it can be called from restart (see patch adding restart of files).

[PATCH v21 037/100] c/r: introduce new 'file_operations': ->checkpoint, ->collect()
While we assume all normal files and directories can be checkpointed, there are, as usual in the VFS, specialized places that will always need an ability to override these defaults. Although we could do this completely in the checkpoint code, that would bitrot quickly. This adds a new 'file_operations' function f... 1 May 2010 10:55

[PATCH v21 017/100] cgroup freezer: interface to freeze a cgroup from within the kernel
Add public interface to freeze a cgroup freezer given a task that belongs to that cgroup: cgroup_freezer_make_frozen(task) Freezing the root cgroup is not permitted. Freezing the cgroup to which current process belong is also not permitted. This will be used for restart(2) to be able to leave the restarted pr... 1 May 2010 10:55

[PATCH v21 019/100] Make file_pos_read/write() public and export kernel_write()
These three are used in a subsequent patch to allow the kernel c/r code to call vfs_read/write() to read and write data to and from the checkpoint image. This patch makes the following changes: 1) Move kernel_write() from fs/splice.c to fs/exec.c to be near kernel_read() 2) Make kernel_read/write() iterate ... 1 May 2010 10:54

[PATCH 1/3] input: mt: Simplify event bypass logic
The input bypass mechanism is only used by the MT events. Since all MT events use bypassing by construction, the current list is a mere duplication of input.h.
