Re: [PATCH v14 05/12] ext4: add dirdata format definitions and access helpers

[sashiko-bot@kernel.org]

> Define the on-disk format for ext4 directory entry extension data.
> 
> The upper four bits of de->file_type indicate the presence of
> optional data stored after the filename NUL terminator.  This patch
> defines flags for LUFID, 64-bit inode numbers, and casefold hash
> data stored in that area.
> 
> Add struct ext4_dirent_data_header to describe variable-length
> extension records and struct ext4_dirent_hash for hash storage used
> by casefold and fscrypt.
> 
> Provide ext4_dirdata_next() to advance to the next extension record
> and ext4_dirent_get_data_len() to compute the total extension data
> length associated with a directory entry.
> 
> No functional changes.
