The commit: 802146c mke2fs: create a regular file if necessary caused a regression on 32-bit machines; the open() fails if the file size is > 4G. Using ext2fs_open_file() fixes it. Resolves: Red Hat Bugzilla #1099892 Signed-off-by: Eric Sandeen <redacted> --- V2: against master! Sorry, first patch was against the bisection point. TBH I don't know if this should be using ext2fs_open_file(), or some other magic like O_LARGEFILE, but this works for me, and we use the stat/fstat wrapper here too, so ...
/me suspects do_write_internal() in create_inode.c should use this too. As for the patch itself, looks good, so Reviewed-by: Darrick J. Wong <redacted> --D
