The same binaries > on native host (s390/31 and arm resp.) will *not* force O_LARGEFILE, so IMO > both are emulation bugs. Three exceptions, actually - parisc open() is another case like that. Native 32bit won't force O_LARGEFILE, the same binary on parisc64 will. Signed-off-by: Al Viro Signed-off-by: Linus Torvalds --- Reading git-diff-tree failed
