2010-06-18Staging: iio: kill off spurious semicolonsMike Frysinger
A bunch of IIO files contain spurious semicolons after function definitions and case statements and if statements. Guess people really like this thing, but kill them anyways so they'll stop spreading via copy & paste with new drivers.

2010-06-18Staging: iio: standardize kconfig/makefile spacing/styleMike Frysinger
Standardize the spacing/style across the IIO build files: - comment block in Kconfigs - newlines at ends of files - trailing lines at ends of files - indent with one tab, not spaces or mixed Signed-off-by: Mike Frysinger <vapier@gentoo.org> Acked-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-06-18Staging: ramzswap: Support generic I/O requestsNitin Gupta
Currently, ramzwap devices (/dev/ramzswapX) can only be used as swap disks since it was hard-coded to consider only the first request in bio vector. Now, we iterate over all the segments in an incoming bio which allows us to handle all kinds of I/O requests. ramzswap devices can still handle PAGE_SIZE aligned and multiple of PAGE_SIZE sized I/O requests only. To ensure that we get always get such requests only, we set following request_queue attributes to PAGE_SIZE: - physical_block_size - logical_block_size - io_min - io_opt Note: physical and logical block sizes were already set equal to PAGE_SIZE and that seems to be sufficient to get PAGE_SIZE aligned I/O. Since we are no longer limited to handling swap requests only, the next few patches rename ramzswap to zram. So, the devices will then be called /dev/zram{0, 1, 2, ...} Usage/Examples: 1) Use as /tmp storage - mkfs.ext4 /dev/zram0 - mount /dev/zram0 /tmp 2) Use as swap: - mkswap /dev/zram0 - swapon /dev/zram0 -p 10 # give highest priority to zram0 Performance: - I/O benchamark done with 'dd' command. Details can be found here: http://code.google.com/p/compcache/wiki/zramperf Summary: - Maximum read speed (approx): - ram disk: 1200 MB/sec - zram disk: 600 MB/sec - Maximum write speed (approx): - ram disk: 500 MB/sec - zram disk: 160 MB/sec Issues: - Double caching: We can potentially waste memory by having two copies of a page -- one in page cache (uncompress) and second in the device memory (compressed). However, during reclaim, clean page cache pages are quickly freed, so this does not seem to be a big problem. - Stale data: Not all filesystems support issuing 'discard' requests to underlying block devices. So, if such filesystems are used over zram devices, we can accumulate lot of stale data in memory. Even for filesystems to do support discard (example, ext4), we need to see how effective it is. - Scalability: There is only one (per-device) de/compression buffer stats. This can lead to significant contention, especially when used for generic (non-swap) purposes.

2010-06-18Staging: ti-st: fix protocol countingNaveen Jain
Older mechanism of counting the number of protocols registered with ST was slow, in-efficient. It used to check the protocol data for NULL for each registration/unregistration.

2010-06-18Staging: ti-st: cleanup sysfs codeNaveen Jain
Remove the older way of communicating with user-space daemon UIM. The older way involved creating of a new kobj and pid sysfs file under it, and sending signal using that pid. Now we communicate via rfkill to user-space UIM. Background: UIM is the user-space daemon which upon notification from ldisc driver, opens the tty, sets default baud and then installs (tiocsetd) the ldisc.

2010-06-18Staging: vt6655: fix up U32 conversionGreg Kroah-Hartman
Commit 902d2411298a6e0b8a473a0163aa4bf6d5c8a073 converted U32 to u32 which you would think would be just fine. Unfortunatly, it seems that VIA only builds their code on a 32bit processor (which makes sense if you think about it), but this doesn't work on x86-64. So fix up the few places where this really wanted to be an unsigned long width.
