2011-10-14ore: Support for short read/writesBoaz Harrosh
Memory conditions and max_bio constraints might cause us to not comply to the full length of the requested IO. Instead of failing the complete IO we can issue a shorter read/write and report how much was actually executed in the ios->length member. All users must check ios->length at IO_done or upon return of ore_read/write and re-issue the reminder of the bytes. Because other wise there is no error returned like before. This is part of the effort to support the pnfs-obj layout driver. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2011-10-14exofs: Support for short read/writesBoaz Harrosh
If at read/write_done the actual IO was shorter then requested, reported in returned ios->length. It is not an error. The reminder of the pages should just be unlocked but not marked uptodate or end_page_writeback. They will be re issued later by the VFS. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2011-10-14ore: Remove check for ios->kern_buff in _prepare_for_striping to laterBoaz Harrosh
Move the check and preparation of the ios->kern_buff case to later inside _write_mirror(). Since read was never used with ios->kern_buff its support is removed instead of fixed. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2011-10-14ore: cleanup: Embed an ore_striping_info inside ore_io_stateBoaz Harrosh
Now that each ore_io_state covers only a single raid group. A single striping_info math is needed. Embed one inside ore_io_state to cache the calculation results and eliminate an extra call. Also the outer _prepare_for_striping is removed since it does nothing. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2011-10-14ore: Only IO one group at a time (API change)Boaz Harrosh
Usually a single IO is confined to one group of devices (group_width) and at the boundary of a raid group it can spill into a second group. Current code would allocate a full device_table size array at each io_state so it can comply to requests that span two groups. Needless to say that is very wasteful, specially when device_table count can get very large (hundreds even thousands), while a group_width is usually 8 or 10. * Change ore API to trim on IO that spans two raid groups. The user passes offset+length to ore_get_rw_state, the ore might trim on that length if spanning a group boundary. The user must check ios->length or ios->nrpages to see how much IO will be preformed. It is the responsibility of the user to re-issue the reminder of the IO. * Modify exofs To copy spilled pages on to the next IO. This means one last kick is needed after all coalescing of pages is done. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2011-10-04ore/exofs: Change the type of the devices array (API change)Boaz Harrosh
In the pNFS obj-LD the device table at the layout level needs to point to a device_cache node, where it is possible and likely that many layouts will point to the same device-nodes. In Exofs we have a more orderly structure where we have a single array of devices that repeats twice for a round-robin view of the device table This patch moves to a model that can be used by the pNFS obj-LD where struct ore_components holds an array of ore_dev-pointers. (ore_dev is newly defined and contains a struct osd_dev *od member) Each pointer in the array of pointers will point to a bigger user-defined dev_struct. That can be accessed by use of the container_of macro. In Exofs an __alloc_dev_table() function allocates the ore_dev-pointers array as well as an exofs_dev array, in one allocation and does the addresses dance to set everything pointing correctly. It still keeps the double allocation trick for the inodes round-robin view of the table. The device table is always allocated dynamically, also for the single device case. So it is unconditionally freed at umount. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2011-10-03ore: Make ore_striping_info and ore_calc_stripe_info publicBoaz Harrosh
The struct ore_striping_info will be used later in other structures. And ore_calc_stripe_info as well. Rename them make struct ore_striping_info public. ore_calc_stripe_info is still static, will be made public on first use. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2011-10-03exofs: Remove unused data_map member from exofs_sb_infoBoaz Harrosh
The struct pnfs_osd_data_map data_map member of exofs_sb_info was never used after mount. In fact all it's members were duplicated by the ore_layout structure. So just remove the duplicated information. Also removed some stupid, but perfectly supported, restrictions on layout parameters. The case where num_devices is not divisible by mirror_count+1 is perfectly fine since the rotating device view will eventually use all the devices it can get.

2011-10-03exofs: Rename struct ore_components comps => ocBoaz Harrosh

2011-09-11[media] vp7045: fix buffer setupFlorian Mickler
dvb_usb_device_init calls the frontend_attach method of this driver which uses vp7045_usb_ob. In order to have a buffer ready in vp7045_usb_op, it has to be allocated before that happens. Luckily we can use the whole private data as the buffer as it gets separately allocated on the heap via kzalloc in dvb_usb_device_init and is thus apt for use via usb_control_msg.

2011-09-10ARM: 7088/1: entry: fix wrong parameter name used in do_thumb_abortJanusz Krzysztofik
Commit be020f8618ca, "ARM: entry: abort-macro: specify registers to be used for macros", while replacing register numbers with macro parameter names, mismatched the name used for r1. For me, this resulted in user space built for EABI with -march=armv4t -mtune=arm920t -mthumb-interwork -mthumb broken on my OMAP1510 based Amstrad Delta (old ABI and no thumb still worked for me though). Fix this by using correct parameter name fsr instead of mismatched psr, used by callers for another purpose.

2011-09-10backlight: Declare backlight_types[] constBart Van Assche
Since backlight_types[] isn't modified, let's declare it const. That was probably the intention of the author of commit bb7ca747f8d6 ("backlight: add backlight type"), via which the "const char const *" construct was introduced. The duplicate const was detected by sparse.
