Subject: [PATCH 3/6] f2fs: skip truncate when verity in progress in ->write_begin()

From: Eric Biggers <>

When an error (e.g. ENOSPC) occurs during f2fs_write_begin() when called
from f2fs_write_merkle_tree_block(), skip truncating the file.  i_size
is not meaningful in this case, and the truncation is handled by
f2fs_end_enable_verity() instead.

Fixes: 60d7bf0f790f ("f2fs: add fs-verity support")
