* [PATCH] Use freezeable workqueues in XFSRafael J. Wysocki2006-12-07
| | | | | | | | | | | | Make the workqueues used by XFS freezeable, so their worker threads don't submit any I/O after the suspend image has been created. Signed-off-by: Rafael J.

* [PATCH] Allow user processes to raise their oom_adj valueGuillem Jover2006-12-07
| | | | | | | | | | | | | | | | | | Currently a user process cannot rise its own oom_adj value (i.e. unprotecting itself from the OOM killer). As this value is stored in the task structure it gets inherited and the unprivileged childs will be unable to rise it. The EPERM will be handled by the generic proc fs layer, as only processes with the proper caps or the owner of the process will be able to write to the file. So we allow only the processes with CAP_SYS_RESOURCE to lower the value, otherwise it will get an EACCES which seems more appropriate than EPERM.

* [PATCH] skip data conversion in compat_sys_mount when data_page is NULLAndrey Mirkin2006-12-07
| | | | | | | | | | | | | | | | | | | OpenVZ Linux kernel team has found a problem with mounting in compat mode. Simple command "mount -t smbfs ..." on Fedora Core 5 distro in 32-bit mode leads to oops: Unable to handle kernel NULL pointer dereference at 0000000000000000 RIP: compat_sys_mount+0xd6/0x290 Process mount (pid: 14656, veid=300, threadinfo ffff810034d30000, task ffff810034c86bc0) Call Trace: ia32_sysret+0x0/0xa The problem is that data_page pointer can be NULL, so we should skip data conversion in this case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is mostly a search and replace as ocfs2_journal_handle is now no more than a container for a handle_t pointer. ocfs2_commit_trans() becomes very straight forward, and we remove some out of date comments / code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | All callers either pass in NULL directly, or a local variable that is already set to NULL. The internals of ocfs2_start_trans() get a nice cleanup as a result. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This gets us rid of a slab we no longer need, as well as removing the majority of what's left on ocfs2_journal_handle. ocfs2_commit_unstarted_handle() has no more real work to do, so remove that function too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Instead we record our state on the allocation context structure which all callers already know about and lifetime correctly. This means the reservation functions don't need a handle passed in any more, and we can also take it off the alloc context. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

It creates a separate note for each of /regs, /fpcr, /lslr, /decr, /decr_status, /mem, /signal1, /signal1_type, /signal2, /signal2_type, /event_mask, /event_status, /mbox_info, /ibox_info, /wbox_info, /dma_info, /proxydma_info, /object-id. A new macro, ARCH_HAVE_EXTRA_NOTES, was created for architectures to specify they have extra elf core notes. A new macro, ELF_CORE_EXTRA_NOTES_SIZE, was created so the size of the additional notes could be calculated and added to the notes phdr entry. A new macro, ELF_CORE_WRITE_EXTRA_NOTES, was created so the new notes would be written after the existing notes. The SPU coredump code resides in spufs. Stub functions are provided in the kernel which are hooked into the spufs code which does the actual work via register_arch_coredump_calls(). A new set of __spufs_<file>_read/get() functions was provided to allow the coredump code to read from the spufs files without having to lock the SPU context for each file read from.
