* md: need another print_sb for mdp_superblock_1Cheng Renquan2009-01-08

* md: use list_for_each_entry macro directlyCheng Renquan2009-01-08
| | | | | | | | | | | | | | | | | The rdev_for_each macro defined in <linux/raid/md_k.h> is identical to list_for_each_entry_safe, from <linux/list.h>, it should be defined to use list_for_each_entry_safe, instead of reinventing the wheel. But some calls to each_entry_safe don't really need a safe version, just a direct list_for_each_entry is enough, this could save a temp variable (tmp) in every function that used rdev_for_each. In this patch, most rdev_for_each loops are replaced by list_for_each_entry, totally save many tmp vars; and only in the other situations that will call list_del to delete an entry, the safe version is used.

* md: raid0: make hash_spacing and preshift sector-based.Andre Noll2009-01-08
| | | | | | | | | | | | | | | | | This patch renames the hash_spacing and preshift members of struct raid0_private_data to spacing and sector_shift respectively and changes the semantics as follows: We always have spacing = 2 * hash_spacing. In case sizeof(sector_t) > sizeof(u32) we also have sector_shift = preshift + 1 while sector_shift = preshift = 0 otherwise. Note that the values of nb_zone and zone are unaffected by these changes because in the sector_div() preceeding the assignement of these two variables both arguments double.

Quite a few 64-bit architectures are using `long' for their s64/u64 types. We should convert them all to `long long'. Update types.h so we use unsigned long long for u64 and fix all warnings in sparc64 code. Tested with an allnoconfig, defconfig and allmodconfig builds. This patch introduces additional warnings in several drivers. These will be dealt with in separate patches.

We are doing a few changes during 2009 to improve patch handling for drivers/media stuff. Currently, v4l-dvb-maintainer list at linuxtv.org were used to to be v4l/dvb driver maintainers ML, in order to keep track of patch merge requests and to receive bug fixes. This list allows posting for everybody, but, in order to avoid spam, the user subscribe/unsubscribe at the ML is moderated. Other development discussions and end-user forums happened on two separated ML (one for V4L and another for DVB). At the beginning of 2009, we've created linux-media@vger.kernel.org, meaning to be the main upstream development mailing list for drivers/media, including V4L and DVB core and drivers. The choice for vger.kernel.org were due to the fact that most of upstream lists are there. Also, its anti-spam filtering rules are better than what we currently have at linuxtv.org. For now, both video4linux-list and linux-dvb ML will remain active, but more focused on end users. It is expected that those lists will gradually be replaced also by linux-media@vger.kernel.org. This patch reflect those changes at linux MAINTAINERS file. Since the development and bug fix discussions will now happen at linux-media@vger.kernel.org, this patch does the following changes - replaces v4l-dvb-maintainer ML for the new linux-media@vger.kernel.org; - replaces video4linux ML for the new linux-media@vger.kernel.org; While here, it also: - Fixes the existing -git tree entries for drivers/media (since the repository name changed); - Adds the missing drivers/media -git tree entry on a few maintainers entries that don't point to a tree.

Just fixing Kconfig could create a very complex set of rules. Also, this hides a problem with the current approach where the dvb functionality weren't confined inside dvb module. What happens is that: - cx88-i2c (part of cx8800) has some special rules if DVB; - cx88-mpeg (cx8802 module) has also part of DVB init code; - cx88-dvb has the rest of the dvb code; - cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not. So, instead of doing some tricks at Kconfig and wait for a next breakage, this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb. Another problem is that cx8802 were being compiled, even without cx88-dvb and cx88-blackbird modules. While on this code, let's fix also a reported problem: http://www.linuxtv.org/pipermail/linux-dvb/2009-January/031225.html A solution for the issue were proposed here: http://www.mail-archive.com/linux-media@vger.kernel.org/msg00021.html Thanks to Randy, Andy, Gregoire and Thomas for helping us to detect and solve the issues.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A number of nfsd operations depend on the i_mutex to cover more code than just the fsync, so the approach of 4c728ef583b3d8 "add a vfs_fsync helper" doesn't work for nfsd. Revert the parts of those patches that touch nfsd. Note: we can't, however, remove the logic from vfs_fsync that was needed only for the special case of nfsd, because a vfs_fsync(NULL,...) call can still result indirectly from a stackable filesystem that was called by nfsd.

This record is common to all transports and can be freed in common code. Move the kfree of the rq_deferred to the common svc_xprt_release function. This also fixes a memory leak in the RDMA transport which does not kfree the dr structure in it's version of the xpo_release_rqst callback.

There are two parts to the problem, both in nfsd_setuser(): (1) The return value of set_groups() is -ve if in error, not 0, and should be checked appropriately. 0 indicates success. (2) The UID to use for fs accesses is in new->fsuid, not new->uid (which is 0). This causes CAP_DAC_OVERRIDE to always be set, rather than being cleared if the UID is anything other than 0 after squashing. Reported-by: J.

| * | | nfsd: Ensure nfsv4 calls the underlying filesystem on LOCKTJ. Bruce Fields2009-01-07

But we forgot to initialize the file operations, with the result that LOCKT never results in a call to the filesystem's ->lock() method (if it exists). We could just add that one more initialization. But this hack of faking up a struct file with only some fields initialized seems the kind of thing that might cause more problems in the future. We should either do an open and get a real struct file, or make lock-testing an inode (not a file) method. This patch does the former.
