24  * This file implements UBIFS extended attributes support.
26  * Extended attributes are implemented as regular inodes with attached data,
27  * which limits extended attribute size to UBIFS block size (4KiB). Names of
28  * extended attributes are described by extended attribute entries (xentries),
31  * In other words, the situation with extended attributes is very similar to
34  * directory entries. Extended attribute entries store the name of the extended
35  * attribute, the host inode number, and the extended attribute inode number.
38  * extended attributes.
40  * The number of extended attributes is not limited, but there is Linux
41  * limitation on the maximum possible size of the list of all extended
43  * the sum of all extended attribute names of the inode does not exceed that
46  * Extended attributes are synchronous, which means they are written to the
47  * flash media synchronously and there is no write-back for extended attribute
48  * inodes. The extended attribute values are not stored in compressed form on
51  * Since extended attributes are represented by regular inodes, they are cached
64  * Limit the number of extended attributes per inode so that the total size
70  * Extended attribute type constants.
72  * USER_XATTR: user extended attribute ("user.*")
73  * TRUSTED_XATTR: trusted extended attribute ("trusted.*)
74  * SECURITY_XATTR: security extended attribute ("security.*")
86  * create_xattr - create an extended attribute.
89  * @nm: extended attribute name
90  * @value: extended attribute value
91  * @size: size of extended attribute value
93  * This is a helper function which creates an extended attribute of name @nm
95  * because the ctime and extended attribute accounting data changes. This
115 	 * Linux limits the maximum size of the extended attribute names list  in create_xattr()
117 	 * extended attributes if the name list becomes larger. This limitation  in create_xattr()
197  * change_xattr - change an extended attribute.
200  * @inode: extended attribute inode
201  * @value: extended attribute value
202  * @size: size of extended attribute value
204  * This helper function changes the value of extended attribute @inode with new
