This patch breaks down sdhci-of into a core portion and a eSDHC portion, clearing the path to easily support additional hardware using the same OF driver. Signed-off-by:

This patch renames sdhci-of.c to sdhci-of-core.c before reorganizing the driver to support additional hardware. The driver is still built as sdhci-of despite the rename of the file. No functional change. Signed-off-by:

Daniel Drake noticed a crash in the error path of mmc_attach_sdio(). This bug is discussed at http://dev.laptop.org/ticket/9707. BUG: unable to handle kernel paging request at 6b6b6c57 IP: [<b066d6e2>] sdio_remove_func+0x9/0x27 Call Trace: [<b066cfb4>] ? mmc_sdio_remove+0x34/0x65 [<b066d1fc>] ? mmc_attach_sdio+0x217/0x240 [<b066a22f>] ? mmc_rescan+0x1a2/0x20f [<b042e9a0>] ? worker_thread+0x156/0x1e We need to accurately track how many SDIO functions have been initialised (and keep card->sdio_funcs in sync) so that we don't try to remove more functions than we initialised if we hit the error path in mmc_attach_sdio(). Without this patch if we hit the error path in mmc_attach_sdio() we run the risk of deferencing invalid memory in sdio_remove_func(), leading to a crash. Signed-off-by:

sdio_remove_func() needs to be more careful about reference counting. It can be called in error paths where sdio_add_func() has never been called e.g. mmc_attach_sdio error path --> mmc_sdio_remove --> sdio_remove_func Signed-off-by:

Thanks to Roland who pointed out de_thread() issues. Currently we add sub-threads to ->real_parent->children list. This buys nothing but slows down do_wait(). With this patch ->children contains only main threads (group leaders). The only complication is that forget_original_parent() should iterate over sub-threads by hand, and de_thread() needs another list_replace() when it changes ->group_leader. Henceforth do_wait_thread() can never see task_detached() && !EXIT_DEAD tasks, we can remove this check (and we can unify do_wait_thread() and ptrace_do_wait()). This change can confuse the optimistic search in mm_update_next_owner(), but this is fixable and minor. Perhaps badness() and oom_kill_process() should be updated, but they should be fixed in any case. Signed-off-by:

sizeof(viafb_gamma_table) is just the size of the pointer. This is changed to the size used when calling kmalloc to initialize the pointer.

It can happen that write does not use all the blocks allocated in write_begin either because of some filesystem error (like ENOSPC) or because page with data to write has been removed from memory.

To iterate: * patch makes impossible to start using ext3 on EXT3_FS=n kernels without reboot. * this is done only for one pointer on task_struct" None of config options which define task_struct are tristate directly or effectively."

This reverts commit e9496ff4. Quoth Al: "it's dependent on a lot of other stuff not currently in mainline and badly broken with current fs/namespace.c. Sorry, badly out-of-order cherry-pick from old queue. PS: there's a large pending series reworking the refcounting and lifetime rules for vfsmounts that will, among other things, allow to rip a subtree away _without_ dissolving connections in it, to be garbage-collected when all active references are gone. It's considerably saner wrt "is the subtree busy" logics, but it's nowhere near being ready for merge at the moment; this changeset is one of the things becoming possible with that sucker, but it certainly shouldn't have been picked during this cycle. My apologies..." Noticed-by:

We recently go rid of all callers of do_sync_file_range as they're better served with vfs_fsync or the filemap_write_and_wait. Now that do_sync_file_range is down to a single caller fold it into it so that people don't start using it again accidentally. While at it also switch it from using __filemap_fdatawrite_range(..., WB_SYNC_ALL) to the more clear filemap_fdatawrite_range(). Signed-off-by:

Filesystems outside the regular namespace do not have to clear DCACHE_UNHASHED in order to have a working /proc/$pid/fd/XXX. Nothing in proc prevents the fd link from being used if its dentry is not in the hash. Also, it does not get put into the dcache hash if DCACHE_UNHASHED is clear; that depends on the filesystem calling d_add or d_rehash. So delete the misleading comments and needless code. Acked-by:

The loop condition is fragile: we compare an unsigned value to zero, and then decrement it by something larger than one in the loop. All the callers should be passing in appropriately aligned buffer lengths, but it's better to just not rely on it, and have some appropriate defensive loop limits. Acked-by:
