Subject: Re:[PATCH 3/4] ext4: factor out write end code of inline file

Hello Yuli:

I think that "(void) ext4_find_inline_data_nolock(inode);" should before 
ext4_write_inline_data(inode, &iloc, kaddr, pos, copied);
Or  the backport cause a regression of commit c481607ba
("ext4: fix race writing to an inline_data file while its xattrs are changing")
