H A Derofs.rst107 (no)user_xattr Setup Extended User Attributes. Note: xattr is enabled
228 Each share xattr can also be directly found by the following formula:
229 xattr offset = xattr_blkaddr * block_size + 4 * xattr_id
236 | ... | xattr_entry | xattr data | ... | xattr_entry | xattr data ...
284 overall idea is that, apart from the existing predefined prefixes, the xattr
285 entry could also refer to user-specified long xattr name prefixes, e.g.
288 When referring to a long xattr name prefix, the highest bit (bit 7) of
293 the full xattr name matches exactly as its long xattr name prefix.
295 All long xattr prefixes are stored one by one in the packed inode as long as
298 long xattr name prefixes, while (xattr_prefix_start * 4) indicates the start

161 xattr tables are written.
278 The xattr table contains extended attributes for each inode. The xattrs
280 name and value field. The type field encodes the xattr prefix
283 is stored inline (in which case the value field contains the xattr value),
290 The xattr lists are packed into compressed 8K metadata blocks.
292 location of the xattr list inside each inode, a 32-bit xattr id
293 is stored. This xattr id is mapped into the location of the xattr
294 list using a second xattr id lookup table.
