ext4: add support for online resizing with bigalloc This patch adds support for online resizing on bigalloc file system by implementing EXT4_IOC_RESIZE_FS ioctl. Old resize interfaces (add block groups and extend last block group) are left untouched. Tests performed with cluster sizes of 1, 2, 4 and 8 blocks (of size 4k) per cluster. I will add these tests to xfstests. Signed-off-by: Harshad Shirwadkar <harshads@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
