27 tristate "CRC-CCITT functions"
29 This option is provided for the case where no in-kernel-tree
30 modules require CRC-CCITT functions, but a module built outside
31 the kernel tree does. Such modules that use library CRC-CCITT
32 functions require M here.
35 tristate "CRC16 functions"
37 This option is provided for the case where no in-kernel-tree
38 modules require CRC16 functions, but a module built outside
39 the kernel tree does. Such modules that use library CRC16
40 functions require M here.
43 tristate "CRC calculation for the T10 Data Integrity Field"
45 This option is only needed if a module that's not in the
46 kernel tree needs to calculate CRC checks for use with the
47 SCSI data integrity subsystem.
50 tristate "CRC ITU-T V.41 functions"
52 This option is provided for the case where no in-kernel-tree
53 modules require CRC ITU-T V.41 functions, but a module built outside
54 the kernel tree does. Such modules that use library CRC ITU-T V.41
55 functions require M here.
58 tristate "CRC32 functions"
62 This option is provided for the case where no in-kernel-tree
63 modules require CRC32 functions, but a module built outside the
64 kernel tree does. Such modules that use library CRC32 functions
68 tristate "CRC7 functions"
70 This option is provided for the case where no in-kernel-tree
71 modules require CRC7 functions, but a module built outside
72 the kernel tree does. Such modules that use library CRC7
73 functions require M here.
76 tristate "CRC32c (Castagnoli, et al) Cyclic Redundancy-Check"
80 This option is provided for the case where no in-kernel-tree
81 modules require CRC32c functions, but a module built outside the
82 kernel tree does. Such modules that use library CRC32c functions
83 require M here. See Castagnoli93.
84 Module will be libcrc32c.

207 tristate "SHM Signal - Generic shared-memory signaling mechanism"
210 Provides a shared-memory based signaling mechansim to indicate
211 memory-dirty notifications between two end-points.
216 tristate "IO-Queue library - Generic shared-memory queue"
220 IOQ is a generic shared-memory-queue mechanism that happens to be
221 friendly to virtualization boundaries. It can be used in a variety
222 of ways, though its intended purpose is to become a low-level
223 communication path for paravirtualized drivers.
