Subject: ext4: simplify ext4_readpage_limit()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5e122148a3d573a66f47f826168a3c23a321ac9d;p=linux.git

ext4: simplify ext4_readpage_limit()

Now that the implementation of FS_IOC_ENABLE_VERITY has changed to not
involve reading back Merkle tree blocks that were previously written,
there is no need for ext4_readpage_limit() to allow for this case.
