[RESEND][PATCH 2/2 v2] ext4: let us fully support punching hole feature in fallocate

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Zheng Liu <wenqing.lz@xxxxxxxxxx>

After adding indirect punching hole feature, we need to enable it in fallocate.
For this purpose, some sanity checks need to be adjusted.  Currently we need to
check FALLOC_FL_PUNCH_HOLE flag before other sanity checks.
