2007-07-16diskquota: 32bit quota tools on 64bit architecturesVasily Tarasov
OpenVZ Linux kernel team has discovered the problem with 32bit quota tools working on 64bit architectures. In 2.6.10 kernel sys32_quotactl() function was replaced by sys_quotactl() with the comment "sys_quotactl seems to be 32/64bit clean, enable it for 32bit" However this isn't right. Look at if_dqblk structure: struct if_dqblk { __u64 dqb_bhardlimit; __u64 dqb_bsoftlimit; __u64 dqb_curspace; __u64 dqb_ihardlimit; __u64 dqb_isoftlimit; __u64 dqb_curinodes; __u64 dqb_btime; __u64 dqb_itime; __u32 dqb_valid; }; For 32 bit quota tools sizeof(if_dqblk) == 0x44. But for 64 bit kernel its size is 0x48, 'cause of alignment! Thus we got a problem. Attached patch reintroduce sys32_quotactl() function, that handles this and related situations.

2007-02-11[PATCH] Common compat_sys_sysinfoKyle McMartin
I noticed that almost all architectures implemented exactly the same sys32_sysinfo... except parisc, where a bug was to be found in handling of the uptime. So let's remove a whole whack of code for fun and profit. Cribbed compat_sys_sysinfo from x86_64's implementation, since I figured it would be the best tested. This patch incorporates Arnd's suggestion of not using set_fs/get_fs, but instead extracting out the common code from sys_sysinfo.

2006-01-10[PATCH] common compat_sys_timer_createChristoph Hellwig
The comment in compat.c is wrong, every architecture provides a get_compat_sigevent() for the IPC compat code already. This basically moves the x86_64 version to common code and removes all the others.

2005-09-07[PATCH] remove duplicated sys_open32() code from 64bit archsMiklos Szeredi
64 bit architectures all implement their own compatibility sys_open(), when in fact the difference is simply not forcing the O_LARGEFILE flag. So use the a common function instead.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
