H A Derofs.rst110 (no)user_xattr Setup Extended User Attributes. Note: xattr is enabled
254 Each share xattr can also be directly found by the following formula:
255 xattr offset = xattr_blkaddr * block_size + 4 * xattr_id
262 | ... | xattr_entry | xattr data | ... | xattr_entry | xattr data ...
309 The long xattr name prefixes feature is introduced to address this issue. The
310 overall idea is that, apart from the existing predefined prefixes, the xattr
311 entry could also refer to user-specified long xattr name prefixes, e.g.
314 When referring to a long xattr name prefix, the highest bit (bit 7) of
318 xattr name prefix is stored in erofs_xattr_entry.e_name, which could be empty if
319 the full xattr name matches exactly as its long xattr name prefix.
