Subject: [PATCH] erofs-utils: do not check ->idata_size for compressed files in erofs_prepare_inode_buffer()
Date: Thu, 17 Jun 2021 16:29:54 +0800	[thread overview]
Message-ID: <20210617082954.1001-1-zbestahu@gmail.com> (raw)

From: Yue Hu <huyue2@yulong.com>

erofs_write_compressed_file() will always set inode->idata_size = 0
if succeed, that means no tail-end data for compressed files. So, no
need to call erofs_prepare_tail_block() which is used to handle
tail-end data for that case. Just skip it.

Also, correct 'a inode' -> 'an inode'.
