2007-07-10SUNRPC: Remove rpc_clnt->cl_countTrond Myklebust
The kref now does most of what cl_count + cl_user used to do. The only remaining role for cl_count is to tell us if we are in a 'shutdown' phase. We can provide that information using a single bit field instead of a full atomic counter. Also rename rpc_destroy_client() to rpc_close_client(), which reflects better what its role is these days.

2007-07-10NFS4: on a O_EXCL OPEN make sure SETATTR sets the fields holding the verifierJeff Layton
The Linux NFS4 client simply skips over the bitmask in an O_EXCL open call and so it doesn't bother to reset any fields that may be holding the verifier. This patch has us save the first two words of the bitmask (which is all the current client has #defines for). The client then later checks this bitmask and turns on the appropriate flags in the sattr->ia_verify field for the following SETATTR call. This patch only currently checks to see if the server used the atime and mtime slots for the verifier (which is what the Linux server uses for this). I'm not sure of what other fields the server could reasonably use, but adding checks for others should be trivial.

2007-07-10Make common helpers for seq_files that work with list_headsPavel Emelianov
Many places in kernel use seq_file API to iterate over a regular list_head. The code for such iteration is identical in all the places, so it's worth introducing a common helpers. This makes code about 300 lines smaller: The first version of this patch made the helper functions static inline in the seq_file.h header. This patch moves them to the fs/seq_file.c as Andrew proposed. The vmlinux .text section sizes are as follows: 2.6.22-rc1-mm1: 0x001794d5 with the previous version: 0x00179505 with this patch: 0x00179135 The config file used was make allnoconfig with the "y" inclusion of all the possible options to make the files modified by the patch compile plus drivers I have on the test node. This patch: Many places in kernel use seq_file API to iterate over a regular list_head. The code for such iteration is identical in all the places, so it's worth introducing a common helpers.

2007-07-10Add LZO1X algorithm to the kernelRichard Purdie
This is a hybrid version of the patch to add the LZO1X compression algorithm to the kernel. Nitin and myself have merged the best parts of the various patches to form this version which we're both happy with (and are jointly signing off). The performance of this version is equivalent to the original minilzo code it was based on. Bytecode comparisons have also been made on ARM, i386 and x86_64 with favourable results. There are several users of LZO lined up including jffs2, crypto and reiser4 since its much faster than zlib.

Common power driver for PDAs and phones with one or two external power supplies (AC/USB) connected to main and backup batteries, and optional builtin charger. It's used to stop logic duplication through different embedded devices. So, power supply *logic* is here. pda_power register power supplies, and will take care about notifying batteries about power changes through external power interface. Currently, power consumption legal limits (including USB power consumption) should be handled by platform code, inside set_charge function.

2007-07-10pipe: change the ->pin() operation to ->confirm()Jens Axboe
The name 'pin' was badly chosen, it doesn't pin a pipe buffer in the most commonly used sense in the kernel. So change the name to 'confirm', after debating this issue with Hugh Dickins a bit.

2007-07-10xip sendfile removalCarsten Otte
This patch removes xip_file_sendfile, the sendfile implementation for xip without replacement. Those customers that use xip on s390 are not using sendfile() as far as we know, and so far s390 is the only platform this could potentially be used on so far. Having sendfile is not a popular feature for execute in place file systems, however we have a working implementation of splice_read() based on fs/splice.c if anyone asks for it. At this point in time, it does not seem preferable to merge splice_read() for xip because it causes extra maintenence effort due to code duplication and it requires struct page behind the xip memory segment. We'd like to get rid of that in favor of supporting flash based embedded platforms (Monta Vista work) soon.

2007-07-10splice: abstract out actor dataJens Axboe
For direct splicing (or private splicing), the output may not be a file.

This is the first step in better splice handling for drivers, and also for implementing vmsplice _to_ user memory. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-07-09ide: add short cables supportBartlomiej Zolnierkiewicz
This patch allows users to override both host and device side cable detection with "ideX=ata66" kernel parameter. Thanks to this it should be now possible to use UDMA > 2 modes on systems (laptops mainly) which use short 40-pin cable instead of 80-pin one. Next patches add automatic detection of some systems using short cables. Changes: * Rename hwif->udma_four to hwif->cbl and make it u8. * Convert all existing users accordingly (use ATA_CBL_* defines while at it). * Add ATA_CBL_PATA40_SHORT support to ide-iops.c:eighty_ninty_three(). * Use ATA_CBL_PATA40_SHORT for "ideX=ata66" kernel parameter.
