There are a range of rbd and libceph cleanups, especially surrounding device setup and teardown, and a few critical fixes in that code. There are more cleanups in the messenger code, virtual xattrs, a fix for CRC calculation/checks, and lots of other miscellaneous stuff. There's a patch from Amon Ott to make inos behave a bit better on 32-bit boxes, some decode check fixes from Xi Wang, and network throttling fix from Jim Schutt, and a couple RBD fixes from Josh Durgin. No new functionality, just a lot of cleanup and bug fixing." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: (65 commits) rbd: move snap_rwsem to the device, rename to header_rwsem ceph: fix three bugs, two in ceph_vxattrcb_file_layout() libceph: isolate kmap() call in write_partial_msg_pages() libceph: rename "page_shift" variable to something sensible libceph: get rid of zero_page_address libceph: only call kernel_sendpage() via helper libceph: use kernel_sendpage() for sending zeroes libceph: fix inverted crc option logic libceph: some simple changes libceph: small refactor in write_partial_kvec() libceph: do crc calculations outside loop libceph: separate CRC calculation from byte swapping libceph: use "do" in CRC-related Boolean variables ceph: ensure Boolean options support both senses libceph: a few small changes libceph: make ceph_tcp_connect() return int libceph: encapsulate some messenger cleanup code libceph: make ceph_msgr_wq private libceph: encapsulate connection kvec operations libceph: move prepare_write_banner() ...
| * | BUG: headers with BUG/BUG_ON etc. need linux/bug.hPaul Gortmaker2012-03-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a header file is making use of BUG, BUG_ON, BUILD_BUG_ON, or any other BUG variant in a static inline (i.e. not in a #define) then that header really should be including <linux/bug.h> and not just expecting it to be implicitly present. We can make this change risk-free, since if the files using these headers didn't have exposure to linux/bug.h already, they would have been causing compile failures/warnings.

* | | libceph: embed ceph messenger structure in ceph_clientAlex Elder2012-06-011-1/+1
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | A ceph client has a pointer to a ceph messenger structure in it. There is always exactly one ceph messenger for a ceph client, so there is no need to allocate it separate from the ceph client structure. Switch the ceph_client structure to embed its ceph_messenger structure.

* | rbd: make ceph_parse_options() return a pointerAlex Elder2012-03-221-1/+1
|/ | | | | | | | | | | | ceph_parse_options() takes the address of a pointer as an argument and uses it to return the address of an allocated structure if successful. With this interface is not evident at call sites that the pointer is always initialized. Change the interface to return the address instead (or a pointer-coded error code) to make the validity of the returned pointer obvious.

* treewide: fix potentially dangerous trailing ';' in #defined values/expressionsPhil Carmody2011-07-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | All these are instances of #define NAME value; or #define NAME(params_opt) value; These of course fail to build when used in contexts like if(foo $OP NAME) while(bar $OP NAME) and may silently generate the wrong code in contexts such as foo = NAME + 1; /* foo = value; + 1; */ bar = NAME - 1; /* bar = value; - 1; */ baz = NAME & quux; /* baz = value; & quux; */ Reported on comp.lang.c, Message-ID: <ab0d55fe-25e5-482b-811e-c475aa6065c3@c29g2000yqd.googlegroups.com> Initial analysis of the dangers provided by Keith Thompson in that thread. There are many more instances of more complicated macros having unnecessary trailing semicolons, but this pile seems to be all of the cases of simple values suffering from the problem. (Thus things that are likely to be found in one of the contexts above, more complicated ones aren't.)

* ceph: factor out libceph from Ceph file systemYehuda Sadeh2010-10-201-0/+249
This factors out protocol and low-level storage parts of ceph into a separate libceph module living in net/ceph and include/linux/ceph. This is mostly a matter of moving files around. However, a few key pieces of the interface change as well: - ceph_client becomes ceph_fs_client and ceph_client, where the latter captures the mon and osd clients, and the fs_client gets the mds client and file system specific pieces. - Mount option parsing and debugfs setup is correspondingly broken into two pieces. - The mon client gets a generic handler callback for otherwise unknown messages (mds map, in this case). - The basic supported/required feature bits can be expanded (and are by ceph_fs_client). No functional change, aside from some subtle error handling cases that got cleaned up in the refactoring process. Signed-off-by: Sage Weil <sage@newdream.net>
