12  * This file implements UBIFS extended attributes support.
14  * Extended attributes are implemented as regular inodes with attached data,
15  * which limits extended attribute size to UBIFS block size (4KiB). Names of
16  * extended attributes are described by extended attribute entries (xentries),
19  * In other words, the situation with extended attributes is very similar to
22  * directory entries. Extended attribute entries store the name of the extended
23  * attribute, the host inode number, and the extended attribute inode number.
26  * extended attributes.
28  * The number of extended attributes is not limited, but there is Linux
29  * limitation on the maximum possible size of the list of all extended
31  * the sum of all extended attribute names of the inode does not exceed that
34  * Extended attributes are synchronous, which means they are written to the
35  * flash media synchronously and there is no write-back for extended attribute
36  * inodes. The extended attribute values are not stored in compressed form on
39  * Since extended attributes are represented by regular inodes, they are cached
52  * Extended attribute type constants.
54  * USER_XATTR: user extended attribute ("user.*")
55  * TRUSTED_XATTR: trusted extended attribute ("trusted.*)
56  * SECURITY_XATTR: security extended attribute ("security.*")
68  * create_xattr - create an extended attribute.
71  * @nm: extended attribute name
72  * @value: extended attribute value
73  * @size: size of extended attribute value
75  * This is a helper function which creates an extended attribute of name @nm
77  * because the ctime and extended attribute accounting data changes. This
97 	 * Linux limits the maximum size of the extended attribute names list  in create_xattr()
99 	 * extended attributes if the name list becomes larger. This limitation  in create_xattr()
179  * change_xattr - change an extended attribute.
182  * @inode: extended attribute inode
183  * @value: extended attribute value
184  * @size: size of extended attribute value
186  * This helper function changes the value of extended attribute @inode with new
227 	 * the extended attribute inode gets synchronized, because it goes  in change_xattr()
