2012-01-08functionfs: unfuck failure exits on mountAl Viro1-20/+11
* if you do dput() of root dentry, do *not* follow that with iput() of root inode. * while we are at it, don't do that dput() at all - you are leaving the pointer in ->s_root and your ->kill_sb() will be very unhappy with that. It will do proper dput(), though, so the easiest way is to leave that to it entirely. * freeing ->s_fs_info is also best left to ->kill_sb() (which will do it anyway), especially since we leave the pointer in place. * that xchg() in ->kill_sb() is not a bug per se, but it's a plain and simple masturbation with fewer excuses than Onan had...

This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file, and it fixes the build error in the arch/x86/kernel/microcode_core.c file, that the merge did not catch. The microcode_core.c patch was provided by Stephen Rothwell <sfr@canb.auug.org.au> who was invaluable in the merge issues involved with the large sysdev removal process in the driver-core tree.

2012-01-06dma-buf: Introduce dma buffer sharing mechanismSumit Semwal3-0/+302
This is the first step in defining a dma buffer sharing mechanism. A new buffer object dma_buf is added, with operations and API to allow easy sharing of this buffer object across devices. The framework allows: - creation of a buffer object, its association with a file pointer, and associated allocator-defined operations on that buffer. This operation is called the 'export' operation. - different devices to 'attach' themselves to this exported buffer object, to facilitate backing storage negotiation, using dma_buf_attach() API. - the exported buffer object to be shared with the other entity by asking for its 'file-descriptor (fd)', and sharing the fd across. - a received fd to get the buffer object back, where it can be accessed using the associated exporter-defined operations. - the exporter and user to share the scatterlist associated with this buffer object using map_dma_buf and unmap_dma_buf operations. Atleast one 'attach()' call is required to be made prior to calling the map_dma_buf() operation. Couple of building blocks in map_dma_buf() are added to ease introduction of sync'ing across exporter and users, and late allocation by the exporter. For this first version, this framework will work with certain conditions: - *ONLY* exporter will be allowed to mmap to userspace (outside of this framework - mmap is not a buffer object operation), - currently, *ONLY* users that do not need CPU access to the buffer are allowed. More details are there in the documentation patch. This is based on design suggestions from many people at the mini-summits[1], most notably from Arnd Bergmann <arnd@arndb.de>, Rob Clark <rob@ti.com> and Daniel Vetter <daniel@ffwll.ch>. The implementation is inspired from proof-of-concept patch-set from Tomasz Stanislawski <t.stanislaws@samsung.com>, who demonstrated buffer sharing between two v4l2 devices.

2012-01-05cnic: Improve error recovery on bnx2x devicesMichael Chan3-8/+74
When a bnx2x device encounters parity errors, it will not respond to all SPQ messages. As a result, the shutdown sequence before reset can take a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout of all such messages. To improve this scenario, when bnx2x returns error on the SPQ, we'll send an immediate response to the ulp drivers to avoid such lengthy timeouts. Adjust the return code of relevant functions to return error only if the message cannot be sent on the SPQ so that we'll generate an error completion to the ulp drivers.

Currently, the refill path for RX buffers will always allocate the buffers as GFP_ATOMIC, even if we are in process context. This will fail to apply memory pressure as the worker thread will not contribute to the freeing of memory.
