2011-05-14tmpfs: fix race between swapoff and writepageHugh Dickins1-6/+4
Shame on me! Commit b1dea800ac39 "tmpfs: fix race between umount and writepage" fixed the advertized race, but introduced another: as even its comment makes clear, we cannot safely rely on a peek at list_empty() while holding no lock - until info->swapped is set, shmem_unuse_inode() may delete any formerly-swapped inode from the shmem_swaplist, which in this case would leave a swap area impossible to swapoff. Although I don't relish taking the mutex every time, I don't care much for the alternatives either; and at least the peek at list_empty() in shmem_evict_inode() (a hotter path since most inodes would never have been swapped) remains safe, because we already truncated the whole file.

2011-05-14Further fbcon sanity checkingBruno Prémont1-4/+4
This moves the if (num_registered_fb == FB_MAX) return -ENXIO; check _AFTER_ the call to do_remove_conflicting_framebuffers() as this would (now in a safe way) allow a native driver to replace the conflicting one even if all slots in registered_fb[] are taken. This also prevents unregistering a framebuffer that is no longer registered (vga16f will unregister at module unload time even if the frame buffer had been unregistered earlier due to being found conflicting).

2011-05-14fbmem: fix remove_conflicting_framebuffers racesLinus Torvalds1-49/+68
When a register_framebuffer() call results in us removing old conflicting framebuffers, the new registration_lock doesn't protect that situation. And we can't just add the same locking to the function, because these functions call each other: register_framebuffer() calls remove_conflicting_framebuffers, which in turn calls unregister_framebuffer for any conflicting entry. In order to fix it, this just creates wrapper functions around all three functions and makes the versions that actually do the work be called "do_xxx()", leaving just the wrapper that gets the lock and calls the worker function. So the rule becomes simply that "do_xxxx()" has to be called with the lock held, and now do_register_framebuffer() can just call do_remove_conflicting_framebuffers(), and that in turn can call _do_unregister_framebuffer(), and there is no deadlock, and we can hold the registration lock over the whole sequence, fixing the races. It also makes error cases simpler, and fixes one situation where we would return from unregister_framebuffer() without releasing the lock, pointed out by Bruno Prémont.

2011-05-13rbd: fix split bio handlingYehuda Sadeh1-20/+151
The rbd driver currently splits bios when they span an object boundary. However, the blk_end_request expects the completions to roll up the results in block device order, and the split rbd/ceph ops can complete in any order. This patch adds a struct rbd_req_coll to track completion of split requests and ensures that the results are passed back up to the block layer in order. This fixes errors where the file system gets completion of a read operation that spans an object boundary before the data has actually arrived. The bug is easily reproduced with iozone with a working set larger than available RAM.

2011-05-13vfs: micro-optimize acl_permission_check()Linus Torvalds1-1/+1
It's a hot function, and we're better off not mixing types in the mask calculations. The compiler just ends up mixing 16-bit and 32-bit operations, for no good reason. So do everything in 'unsigned int' rather than mixing 'unsigned int' masking with a 'umode_t' (16-bit) mode variable. This, together with the parent commit (47a150edc2ae: "Cache user_ns in struct cred") makes acl_permission_check() much nicer. Signed-off-by: Linus Torvalds <[email protected]>

2011-05-13ocfs2/cluster: Increase the live threshold for global heartbeatSunil Mushran1-1/+12
We have seen isolated cases (very few, I might add) of o2hb not detecting all live nodes on startup. One plausible reasoning for it is that other node had a hb io delay at the same time. The live threshold set at 2 (as low as it can be) could be increased to ameliorate the situation. But increasing the threshold directly affects mount time. Currently it takes around 5 secs to mount a volume in o2cb cluster with local heartbeat. Increasing the threshold will make mounts even slower. As the issue itself is rare, we have left things as they are for the local heartbeat mode. However we can improve the situation for global heartbeat mode as in that mode, we start the heartbeat much before the mount. This patch doubles the live threshold for the start of the first region in global heartbeat mode. Addresses internal Oracle bug#10635585.

2011-05-12x86: Fix UV BAU for non-consecutive nasidsCliff Wickman2-33/+76
This is a fix for the SGI Altix-UV Broadcast Assist Unit code, which is used for TLB flushing. Certain hardware configurations (that customers are ordering) cause nasids (numa address space id's) to be non-consecutive. Specifically, once you have more than 4 blades in a IRU (Individual Rack Unit - or 1/2 rack) but less than the maximum of 16, the nasid numbering becomes non-consecutive. This currently results in a 'catastrophic error' (CATERR) detected by the firmware during OS boot. The BAU is generating an 'INTD' request that is targeting a non-existent nasid value. Such configurations may also occur when a blade is configured off because of hardware errors. (There is one UV hub per blade.) This patch is required to support such configurations. The problem with the tlb_uv.c code is that is using the consecutive hub numbers as indices to the BAU distribution bit map. These are simply the ordinal position of the hub or blade within its partition. It should be using physical node numbers (pnodes), which correspond to the physical nasid values. Use of the hub number only works as long as the nasids in the partition are consecutive and increase with a stride of 1. This patch changes the index to be the pnode number, thus allowing nasids to be non-consecutive. It also provides a table in local memory for each cpu to translate target cpu number to target pnode and nasid. And it improves naming to properly reflect 'node' and 'uvhub' versus 'nasid'.

2011-05-12ne-h8300: Fix regression caused during net_device_ops conversionGeert Uytterhoeven2-9/+9
Changeset dcd39c90290297f6e6ed8a04bb20da7ac2b043c5 ("ne-h8300: convert to net_device_ops") broke ne-h8300 by adding 8390.o to the link. That meant that lib8390.c was included twice, once in ne-h8300.c and once in 8390.c, subject to different macros. This patch reverts that by avoiding the wrappers in 8390.c. Fix based on commits 217cbfa856dc1cbc2890781626c4032d9e3ec59f ("mac8390: fix regression caused during net_device_ops conversion") and 4e0168fa4842e27795a75b205a510f25b62181d9 ("mac8390: fix build with NET_POLL_CONTROLLER").

This reverts commit 49183b2818de6899383bb82bc032f9344d6791ff. Quoth Franz Melchior: "This patch introduces a bug on my infamous "Acer Travelmate 5735Z-452G32Mnss": when KMS takes over, the frame buffer contents get completely garbled up on screen, with colored stripes and unreadable text (photo on request). Only when X11 is started, the screen gets restored again. Closing and re-opening the lid partly cures the mess, too: it makes the font readable, though horizontally stretched."

2011-05-12x86/mm: Fix section mismatch derived from native_pagetable_reserve()Sedat Dilek1-1/+1
With CONFIG_DEBUG_SECTION_MISMATCH=y I see these warnings in next-20110415: LD vmlinux.o MODPOST vmlinux.o WARNING: vmlinux.o(.text+0x1ba48): Section mismatch in reference from the function native_pagetable_reserve() to the function .init.text:memblock_x86_reserve_range() The function native_pagetable_reserve() references the function __init memblock_x86_reserve_range(). This is often because native_pagetable_reserve lacks a __init annotation or the annotation of memblock_x86_reserve_range is wrong. This patch fixes the issue.
