Separate out the little bit of logic in fh_verify that checks the i_mode into a separate function. This is nicely encapsulated, fh_verify() is overly long anyway, and this change helps make a subsequent nfs4 named attribute change clearer. Signed-off-by:

Attached is a patch that adds CONFIG_INITRAMFS_SOURCE, enabling you to either specify a file as cpio_list, or a directory to generate a list from. It depreciate the INITRAMFS_LIST environment variable introduced not long ago. There are some issues (suggestions/patches welcome) that I am not sure about: 1) I put the menu entry under block devices, but I am not sure if this is the correct location? 2) There might be a better (or more correct) way to do this with kbuild? 3) Variable names and especially help text needs some love. 4) I am not sure if I am duplicating work in progress?

This patch makes gen_init_cpio generate the initramfs_data.cpio from a file which contains a list of entries: file, dir, nod. I swapped the order of filename/location for the file arguments so that it would be more uniform with the dir and node tyes. Signed-off-by:

The problem is that dvb is way to much work-in-progress right now, it's almost impossible to build something which works on both mainline kernel + latest dvb cvs. Hope at least the interfaces are settled soon, for now I gave up on getting it work in mainline in short-term. The patch below compiles the DVB card configuration code only when VIDEO_CX88_DVB is enabled (which is commented right now in Kconfig due to being broken). Signed-off-by:

This is a major update of the cx88 driver. Main new feature is support for the MPEG PCI function of the cx2388x chips. The changes in detail: * A bunch of code restructions, to allow multiple modules (one per PCI function) work on top of the core module. * Add a new module with common code for the mpeg PCI function. * Add a new module to support mpeg encoder cards (connexant "blackbird" reference design). That one is not much tested yet and may have bugs. They can be easily workarounded by not loading the module through, it isn't needed to capture uncompressed video. * Add a new module to support DVB cards. That one is better tested than the blackbird one, but it needs additional cutting-edge stuff from the dvb project, thats why it is disabled in Kconfig for now. * Several cleanups along the way: use kthread, use msleep(), drop some 2.4.x compatibility code, move insmod options to 2.6 style, ... * adapt code to the video-buf changes. * suspend fixes. * as usual some new tv cards.

This update for the bttv driver. Changes: * adapt the driver to video-buf changes. * It also added sanity checks for the bt878 risc code buffer sizes. * adds support for new tv cards. * cleanup i2c driver autoload. * misc cleanups (msleep, ...). * fix IRQ bug when stopping vbi capture. * drop check for cx2388x (bt878 successor) and the printk saying bttv doesn't support these. * set i2c class correctly for dvb cards.

This patch adapts the saa7146 driver to the video-buf changes. Signed-off-by:
-
Gerd Knorr authored
This patch makes the video-buf helper module pass through a void pointer instead of a struct file pointer, that makes the code also usable when no file pointer is available. This is needed for when using the video-buf infrastructure to manage DMA buffers for DVB cards. The file pointer was used by the videobuf_queue_ops callbacks to get the drivers private data via file->private_data, now a pointer to the drivers's private data can be passed directly. Adaptions of the drivers follow with separate patches. Signed-off-by:

Let's lighten the global spinlock mmlist_lock. What's it for? 1. Its original role is to guard mmlist. 2. It later got a second role, to prevent get_task_mm from raising mm_users from the dead, just after it went down to 0. Firstly consider the second: __exit_mm sets tsk->mm NULL while holding task_lock before calling mmput; so mmlist_lock only guards against the exceptional case, of get_task_mm on a kernel workthread which did AIO's use_mm (which transiently sets its tsk->mm without raising mm_users) on an mm now exiting. Well, I don't think get_task_mm should succeed at all on use_mm tasks. It's mainly used by /proc/pid and ptrace, seems at best confusing for those to present the kernel thread as having a user mm, which it won't have a moment later. Define PF_BORROWED_MM, set in use_mm, clear in unuse_mm (though we could just leave it), get_task_mm give NULL if set. Secondly consider the first: and what's mmlist for? 1. Its original role was for swap_out to scan: rmap ended that in 2.5.27. 2. In 2.4.10 it got a second role, for try_to_unuse to scan for swapoff. So, make mmlist a list of mms which maybe have pages on swap: add mm to mmlist when first swap entry is assigned in try_to_unmap_one (pageout), or in copy_page_range (fork); and mmput remove it from mmlist as before, except usually list_empty and there's no need to lock. drain_mmlist added to swapoff, to empty out the mmlist if no swap is then in use. mmput leave mm on mmlist until after its exit_mmap, so try_to_unmap_one can still add mm to mmlist without worrying about the mm_users 0 case; but try_to_unuse must avoid the mm_users 0 case (when an mm might be removed from mmlist, and freed, while it's down in unuse_process): use atomic_inc_return now all architectures support that. Some of the detailed comments in try_to_unuse have grown out of date: updated and trimmed some, but leave SWAP_MAP_MAX for another occasion. Signed-off-by:

The low byte of FAT's first entry must have same value with media-field. So, I added that validity check for some case. In fact, in some case this check detected non-FAT filesystem. But in real world, unfortunately too many devices is writing a wrong value. This patch removes that validity check. Signed-off-by:

This rewrites the cache stuff for file allocation table (FAT). This cache stocks the more pieces of FAT-chain by counting the number of contiguous data blocks. And if cache hit, since a block number can calculate without looking FAT-chain up, fat_get_block() become more fast. But if data blocks was fragmenting, unfortunately this cache is unuseful. read from block device [1st]# time dd if=/dev/hda6 of=/dev/null bs=1M count=2048 2147483648 bytes transferred in 229.524189 seconds (9356241 bytes/sec) real 3m49.557s, user 0m0.026s, sys 1m20.414s [2nd]# time dd if=/dev/hda6 of=/dev/null bs=1M count=2048 2147483648 bytes transferred in 229.539358 seconds (9355623 bytes/sec) real 3m49.647s, user 0m0.036s, sys 1m20.144s read from full contiguous file with this patch [1st]# time dd if=data of=/dev/null bs=1M count=2048 2147483648 bytes transferred in 337.959477 seconds (6354264 bytes/sec) real 5m37.970s, user 0m0.031s, sys 1m21.915s [2nd]# time dd if=data of=/dev/null bs=1M count=2048 2147483648 bytes transferred in 225.401699 seconds (9527362 bytes/sec) real 3m45.476s, user 0m0.027s, sys 1m19.286s read from full fragmented file with this patch [1st]# time dd if=data of=/dev/null bs=1M count=2048 2147483647 bytes transferred in 1146.529081 seconds (1873030 bytes/sec) real 19m6.538s, user 0m0.020s, sys 1m32.774s [2nd]# time dd if=data of=/dev/null bs=1M count=2048 2147483647 bytes transferred in 1045.084822 seconds (2054841 bytes/sec) real 17m25.152s, user 0m0.022s, sys 1m34.801s read from full contiguous file without this patch [1st]# time dd if=data of=/dev/null bs=1M count=2048 2147483648 bytes transferred in 348.144707 seconds (6168365 bytes/sec) real 5m48.169s, user 0m0.019s, sys 1m29.962s [2nd]# time dd if=data of=/dev/null bs=1M count=2048 2147483648 bytes transferred in 324.017361 seconds (6627681 bytes/sec) real 5m24.038s, user 0m0.023s, sys 1m20.602s read from full fragmented file without this patch [1st]# time dd if=data of=/dev/null bs=1M count=2048 2147483647 bytes transferred in 1156.845693 seconds (1856327 bytes/sec) real 19m16.855s, user 0m0.031s, sys 1m32.172s [2nd]# time dd if=data of=/dev/null bs=1M count=2048 2147483647 bytes transferred in 1066.518713 seconds (2013545 bytes/sec) real 17m46.526s, user 0m0.023s, sys 1m33.630s Signed-off-by:
