Updating i_disksize without acquiring i_data_sem semaphore

[Rohit Singh <rohitsd1409@xxxxxxxxx>]

Hello.
I am looking around ext4 code and I observed the following issue.

Within ext4_insert_range(), EXT4_I(inode)->i_disksize is being updated
without acquiring i_data_sem.

I have seen code where this operation is done after acquiring
i_data_sem such as in
ext4_update_i_disksize()

So, is this as expected or is it problematic?

Regards,
Rohit
