* a bug in ramfs_nommu_resize function, passing old size to vmtruncateBryan Wu2007-05-30
| | | | | | | | | | | | It should be pass "newsize" to vmtruncate function to modify the inode->i_size, while the old size is passed to vmtruncate. This bug was caught by LTP truncate test case on Blackfin platform. After it was fixed, the LTP truncate test case passed.

* NFS: Fix a refcount leakage in O_DIRECTTrond Myklebust2007-05-30
| | | | | | | | | | | | | | | | The current code is leaking a reference to dreq->kref when the calls to nfs_direct_read_schedule() and nfs_direct_write_schedule() return an error. This patch moves the call to kref_put() from nfs_direct_wait() back into nfs_direct_read() and nfs_direct_write() (which are the functions that actually took the reference in the first place) fixing the leak. Thanks to Denis V. Lunev for spotting the bug and proposing the original fix. Acked-by: Denis V.

* [XFS] Write at EOF may not update filesize correctly.David Chinner2007-05-29
| | | | | | | | | | | | | | | | | The recent fix for preventing NULL files from being left around does not update the file size corectly in all cases. The missing case is a write extending the file that does not need to allocate a block. In that case we used a read mapping of the extent which forced the use of the read I/O completion handler instead of the write I/O completion handle. Hence the file size was not updated on I/O completion.

* fix compat console unimap regressionHugh Dickins2007-05-25
| | | | | | | | | | | | | | | | | | | | | | Why is it that since the 2f1a2ccb9c0de632ab07193becf5f7121794f6ae console UTF-8 fixes went into 2.6.22-rc1, the PowerMac G5 shows only inverse video question marks for the text on tty2-6? whereas tty1 is fine, and so is x86. No fault of that patch: by removing the old fallback behaviour, it reveals that 32-bit setfont running on 64-bit kernels has only really worked on the current console, the rest getting faked by that inadequate fallback. Bring the compat do_unimap_ioctl into line with the main one: PIO_UNIMAP and GIO_UNIMAP apply to the specified tty, not redirected to fg_console. Use the same checks, and most particularly, remember to check access_ok: con_set_unimap and con_get_unimap are using __get_user and __put_user. And the compat vt_check should ask for the same capability as the main one, CAP_SYS_TTY_CONFIG rather than CAP_SYS_ADMIN. Added in vt_ioctl's vc_cons_allocated check for safety, though failure may well be impossible.

| * NFS: Avoid a deadlock situation on writeTrond Myklebust2007-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | When processes are allowed to attempt to lock a non-contiguous range of nfs write requests, it is possible for generic_writepages to 'wrap round' the address space, and call writepage() on a request that is already locked by the same process. We avoid the deadlock by checking if the page index is contiguous with the list of nfs write requests that is already held in our nfs_pageio_descriptor prior to attempting to lock a new request.

* | Detach sched.h from mm.hAlexey Dobriyan2007-05-21

By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).

This means the allocation of radix tree nodes is done with GFP_NOFS and the allocation of a new page is done using GFP_NOFS. The mapping has a flags field that contains the necessary allocation flags for the page cache allocation. These need to be consulted in order to get DMA and HIGHMEM allocations etc right.

* | NFS4: Fix incorrect use of sizeof() in fs/nfs/nfs4xdr.cTrond Myklebust2007-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The XDR code should not depend on the physical allocation size of structures like nfs4_stateid and nfs4_verifier since those may have to change at some future date. We therefore replace all uses of sizeof() with constants like NFS4_VERIFIER_SIZE and NFS4_STATEID_SIZE. This also has the side-effect of fixing some warnings of the type format ‘%u’ expects type ‘unsigned int’, but argument X has type ‘long unsigned int’ on 64-bit systems Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
