JFS: Add back directory i_size calculations for legacy partitions (dd8a306a) · Commits · 戴 / test

Linux-formatted jfs partitions have a different idea about what i_size represents than partitions formatted on OS/2. The i_size calculation is now based on the size of the directory index. For legacy partitions, which have no directory index, the i_size is never being updated. This patch adds back the original i_size calculations for legacy partitions. Signed-off-by:
