Because inodes remain in cache much longer than inode buffers do under memory pressure, we can get the situation where we have stale, dirty inodes being reclaimed but the backing storage has been freed. Hence we should never, ever flush XFS_ISTALE inodes to disk as there is no guarantee that the backing buffer is in cache and still marked stale when the flush occurs.

We currently have some rather odd code in xfs_setattr for updating the a/c/mtime timestamps: - first we do a non-transaction update if all three are updated together - second we implicitly update the ctime for various changes instead of relying on the ATTR_CTIME flag - third we set the timestamps to the current time instead of the arguments in the iattr structure in many cases. This patch makes sure we update it in a consistent way: - always transactional - ctime is only updated if ATTR_CTIME is set or we do a size update, which is a special case - always to the times passed in from the caller instead of the current time The only non-size caller of xfs_setattr that doesn't come from the VFS is updated to set ATTR_CTIME and pass in a valid ctime value.

Using DECLARE_EVENT_CLASS allows us to to use trace event code instead of duplicating it in the binary. This was not available before 2.6.33 so it had to be done as a separate step once the prerequisite was merged. This only requires changes to xfs_trace.h and the results are rather impressive: hch@brick:~/work/linux-2.6/obj-kvm$ size fs/xfs/xfs.o* text data bss dec hex filename 607732 41884 3616 653232 9f7b0 fs/xfs/xfs.o 1026732 41884 3808 1072424 105d28 fs/xfs/xfs.o.old Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NAlex Elder <aelder@sgi.com>

__per_cpu_idtrs is statically allocated ... on CONFIG_NR_CPUS=4096 systems it hogs 16MB of memory. This is way too much for a quite probably unused facility (only KVM uses dynamic TR registers). Change to an array of pointers, and allocate entries as needed on a per cpu basis. Change the name too as the __per_cpu_ prefix is confusing (this isn't a classic <linux/percpu.h> type object).

Blackfin needs it own arch specific probe_kernel_read() and probe_kernel_write(). This was moved out of the kgdb code and into the arch/blackfin/maccess.c, because it is a generic kernel api. The arch specific kgdb.c for blackfin was cleaned of all functions which exist in the kgdb core that do the same thing after resolving the probe_kernel_read() and probe_kernel_write(). This also eliminated the need for most of the #include's.

reiserfs_get_acl is usually not called under the reiserfs lock, as it doesn't need it. But it happens when it is called by reiserfs_acl_chmod(), which creates a dependency inversion against the private xattr inodes mutexes for the given inode. We need to call it without the reiserfs lock, especially since it's unnecessary.

There is a possibility of a loop happening in the PLL output clock chain on the S3C64XX series. clk_mpll's parent was set to be clk_mout_mpll, but this is fed from clk_fout_epll (which is also clk_mpll). clk_mpll is meant to be the output from the MPLL, and clk_mout_mpll is a seperate clock derived from the mux of clk_mpll and clk_fin_mpll and thus should be considered a seperate clock. Anything using clk_mpll directly really should not be relying on this being the clock that is eventually routed to a peripheral, so remove the loop and ensure that the clocks accurately represent the clock chain in the device. The clk_mpll is not being used outside of the s3c6400-clock.c code, so this change should not break anything else. Do the same for the EPLL. Signed-off-by: NBen Dooks <ben-linux@fluff.org>

The MMU code uses the copy_*_user_page() variants in access_process_vm() rather than copy_*_user() as the former includes an icache flush. This is important when doing things like setting software breakpoints with gdb. So switch the NOMMU code over to do the same. This patch makes the reasonable assumption that copy_from_user_page() won't fail - which is probably fine, as we've checked the VMA from which we're copying is usable, and the copy is not allowed to cross VMAs. The one case where it might go wrong is if the VMA is a device rather than RAM, and that device returns an error which - in which case rubbish will be returned rather than EIO.
