Original code attempts to retry PLOGIs to fcports that are FCP_TARGETs only. If the driver never performed a successful PLOGI/PRLI, the port-type would never be assigned, and the relogin logic would silently drop the request (and thus the port would not be recognized and registered). The fix is relatively straightforward, drop the FCP_TARGET-only check. Signed-off-by:

There's a problem where sg is executing a ->nopage operation on a compound page, it actually calls get_page() on the first page in the compound rather than the page which is being mapped. The fix is to select the correct page by indexing into the compound. Signed-off-by:

Stall error handler if attempting resets/aborts while an rport is blocked. This avoids device offline scenarios due to errors in the error handler. Background: Although the transport is using the scsi_timed_out functionality to restart the timeout if the rport is blocked, if the timeout has already fired before the block occurs, the eh handler still runs and can take the device offline. Ultimately, this window cannot be resolved without significant work in the error handler thread. Christoph noted the first level of these issues when he noted the poor error response handling by the error thread. We found, under heavy load and error testing, that time window from when the scsi_times_out() adds the io to the queue to when the scsi_error_handler gets around to servicing it, can be in the several seconds range. In most cases, these test conditions are highly unusual, but possible. As a result, we're stalling the error handler in this race window so that we can avoid the device_offline transitions.

This patch corrects a problem in mptfc which can result in targets being removed after executing an "lsiutil 99" reset of the fibre channel ports. The last rescan event was being processed before the setup reset work due to an inappropriate optimization in the event processing logic. Every rescan event is now queued for execution and the setup reset work now executes in the proper sequence. Signed-off-by:

The hptiop just got merged with a horrible amount of really bad ioctl code that is against the standards for new scsi drivers. This patch backs it out (and fixes a small bug where scsi_add_host is called to early). We can re-add proper APIs once we agree on them. Signed-off-by:

Currently it is impossible to reset provided by Qlogic QLA2xxx driver SCSI devices externally using corresponding sg devices, particularly via sg_reset utility, because qla2xxx driver in qla2xxx_eh_device_reset() function checks if the input scsi_cmnd has its private data (CMD_SP()) attached. Then the found pointer isn't used anywhere inside of qla2xxx_eh_device_reset(). If the RESET request comes from sg device, it doesn't have such private data. The attached patch removes check for non-NULL CMD_SP() from qla2xxx_eh_device_reset(), hence allows to reset QLA2xxx's devices using corresponding sg devices. AV: change applies to bus/host reset handlers as well. Signed-off-by:

While busy-waiting for completion, check the hardware after scheduling; don't schedule and then immediately check the _timeout_. If the yield() took a long time (as it does on my OLPC prototype board when it's busy), we'd report a timeout even though the hardware was now ready. This fixes it, and also switches the yield() for a cond_resched() because we don't actually want to be _that_ nice about it. I see nice tightly-packed SMBus transactions now, rather than waiting for milliseconds between successive phases. Actually, we shouldn't be busy-waiting here at all. We should be using interrupts. That's an exercise for another day though. Signed-off-by:

I saw an oops down this path when trying to create a new file on a UDF filesystem which was internally marked as readonly, but mounted rw: udf_create udf_new_inode new_inode alloc_inode udf_alloc_inode udf_new_block returns EIO due to readonlyness iput (on error) udf_put_inode udf_discard_prealloc udf_next_aext udf_current_aext udf_get_fileshortad OOPS the udf_discard_prealloc() path was examining uninitialized fields of the udf inode. udf_discard_prealloc() already has this code to short-circuit the discard path if no extents are preallocated: if (UDF_I_ALLOCTYPE(inode) == ICBTAG_FLAG_AD_IN_ICB || inode->i_size == UDF_I_LENEXTENTS(inode)) { return; } so if we initialize UDF_I_LENEXTENTS(inode) = 0 earlier in udf_new_inode, we won't try to free the (not) preallocated blocks, since this will match the i_size = 0 set when the inode was initialized.

A patch in -mm kernel correct the parsing of "address resources" of pnpacpi. Before we assumed it was memory only, but it could be also IO. But this change show an hidden bug : some resources could be producer type that are not handled by pnp layer. So we should ignore the producer resources. This patch fixes bug 6292 (http://bugzilla.kernel.org/show_bug.cgi?id=6292). Some devices like PNP0A03 have 0xd00-0xffff and 0x0-0xcf7 as IO producer resources. Before correcting "address resources" parsing, it was seen as memory and was harmless, because nobody tried to reserve this memory range as it should be IO. With the correction it become IO resources, and make failed all others device that want to register IO in this range and use pnp layer (like a ISA sound card). The solution is to ignore producer resources Signed-off-by:

reiserfs_write_full_page does zero bytes in the file past eof, but it may call get_block on those buffers as well. On machines where the page size is larger than the blocksize, this can result in mmaped files incorrectly growing up to a block boundary during writepage. The fix is to avoid calling get_block for any blocks that are entirely past eof Signed-off-by:

This patch is for collision check enhancement for memory hot add. It's better to do resouce collision check before doing memory hot add, which will touch memory management structures. And add_section() should check section exists or not before calling sparse_add_one_section(). (sparse_add_one_section() will do another check anyway. but checking in memory_hotplug.c will be easy to understand.) Signed-off-by:

add_memory() does all necessary check to avoid collision. then, acpi layer doesn't have to check region by itself. (*) pfn_valid() just returns page struct is valid or not. It returns 0 if a section has been already added even is ioresource is not added. ioresource collision check in mm/memory_hotplug.c can do more precise collistion check. added enabled bit check just for sanity check..

find_next_system_ram() returns valid memory range which meets requested area, only used by memory-hot-add. This function always rewrite requested resource even if returned area is not fully fit in requested one. And sometimes the returnd resource is larger than requested area. This annoyes the caller. This patch changes the returned value to fit in requested area. Signed-off-by:

ioresouce handling code in memory hotplug allows not-aligned memory hot add. But when memmap and other memory structures are initialized, parameters should be aligned. (if not aligned, initialization of mem_map will do wrong, it assumes parameters are aligned.) This patch fix it. And this patch allows ioresource collision check to handle -EEXIST. Signed-off-by:

In bugzilla #6941, Jens Kilian reported: "The function befs_utf2nls (in fs/befs/linuxvfs.c) writes a 0 byte past the end of a block of memory allocated via kmalloc(), leading to memory corruption. This happens only for filenames which are pure ASCII and a multiple of 4 bytes in length. [...] Without DEBUG_SLAB, this leads to further corruption and hard lockups; I believe this is the bug which has made kernels later than 2.6.8 unusable for me. (This must be due to changes in memory management, the bug has been in the BeFS driver since the time it was introduced (AFAICT).) Steps to reproduce: Create a directory (in BeOS, naturally :-) with files named, e.g., "1", "22", "333", "4444", ... Mount it in Linux and do an "ls" or "find"" This patch implements the suggested fix. Credits to Jens Kilian for debugging the problem and finding the right fix. Signed-off-by:
