* [PATCH] device-mapper raid1: drop mark_region spinlock fixJonathan E Brassow2005-11-221-11/+9Star
| | | | | | | | | | | | | | | The spinlock region_lock is held while calling mark_region which can sleep. Drop the spinlock before calling that function. A region's state and inclusion in the clean list are altered by rh_inc and rh_dec. The state variable is set to RH_CLEAN in rh_dec, but only if 'pending' is zero. It is set to RH_DIRTY in rh_inc, but not if it is already so. The changes to 'pending', the state, and the region's inclusion in the clean list need to be atomicly.

* [PATCH] device-mapper: mirror log bitset fixAlasdair G Kergon2005-11-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The linux bitset operators (test_bit, set_bit etc) work on arrays of "unsigned long". dm-log uses such bitsets but treats them as arrays of uint32_t, only allocating and zeroing a multiple of 4 bytes (as 'clean_bits' is a uint32_t). The patch below fixes this problem. The problem is specific to 64-bit big endian machines such as s390x or ppc-64 and can prevent pvmove terminating. In the simplest case, if "region_count" were (say) 30, then bitset_size (below) would be 4 and bitset_uint32_count would be 1. Thus the memory for this butset, after allocation and zeroing would be 0 0 0 0 X X X X On a bigendian 64bit machine, bit 0 for this bitset is in the 8th byte! (and every bit that dm-log would use would be in the X area). 0 0 0 0 X X X X ^ here which hasn't been cleared properly. As the dm-raid1 code only syncs and counts regions which have a 0 in the 'sync_bits' bitset, and only finishes when it has counted high enough, a large number of 1's among those 'X's will cause the sync to not complete. It is worth noting that the code uses the same bitsets for in-memory and on-disk logs. As these bitsets are host-endian and host-sized, this means that they cannot safely be moved between computers with Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Alasdair G Kergon <agk@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] device-mapper: list_versions fixAlasdair G Kergon2005-11-221-1/+1
| | | | | | | | | | | | | | | | | In some circumstances the LIST_VERSIONS output is truncated because the size calculation forgets about a 'uint32_t' in each structure - but the inclusion of the whole of ALIGN_MASK frequently compensates for the omission. This is a quick workaround to use an upper bound. (The code ought to be fixed to supply the actual size.) Running 'dmsetup targets' may demonstrate the problem: when I run it, the last line comes out as 'erro' instead of 'error'. Consequently, 'lvcreate --type error' doesn't work.

* [PATCH] vgacon: Fix usage of stale height value on vc initializationAntonino A. Daplas2005-11-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Reported by: Wayne E. Harlan "[1.] One line summary of the problem: When the kernel option "vga=1" is used, additional tty's (alt+control+Fx with x=2,3,4,5, etc) do not provide the full 50 lines of output. The first one does have 50 lines, however. [2.] Full description of the problem/report: These addtitional tty's show only 39 lines plus the top pixel of the 40-th line. The remaining lines are black and not shown. Kernel version 2.6.13.4 does not show this problem." This bug is caused by using a stale font height value on vgacon_init. Booting with vga=1 gives an 80x50 screen with an 8x8 font. Somewhere during the initialization, the font was changed to 8x9 and the first vc was correctly resized to 80x44. However, the rest of the vc's were not allocated yet, and when they were subsequently initialized, they still used a font height of 8 (instead of 9) causing the mentioned bug. Fix by saving the new font height to vga_video_font_height.

This driver currently "knows" only about Fujitsu-Siemens Amilo Pro V2000 (i.e. it can detect the laptop using DMI and it contains the keycode->key meaning mapping for this laptop) and Xeron SonicPro X 155G (probably can't be reliably autodetected, requires a module parameter), adding other laptops should be easy. In addition to reporting button presses to the input layer the driver also allows enabling/disabling the embedded wireless NIC (using the "Wifi" button); this is done using the same BIOS interface, so it seems only logical to keep the implementation together. Any flexibility possibly gained by allowing users to remap the function of the "Wifi" button is IMHO not worth it when weighted against the necessity to run an user-space daemon to convert button presses to wifi state changes.
