= Prominent features in Linux 3.7 =

= Driver and architecture-specific changes =
All the driver and architecture-specific changes can be found in the [http://kernelnewbies.org/Linux_3.7_DriverArch Linux_3.7_DriverArch page]
= Various core changes =
 * VFS: don't do protected {sym,hard}links by default (breaks things) [http://git.kernel.org/linus/;a=commit;h=561ec64ae67ef25cac8d72bb9c4bfc955edfd415 (commit)]



= Memory Management =
= Networking =
 * Near Field Communication (NFC): Add an Link Layer Control(LLC) Core layer to HCI [http://git.kernel.org/linus/;a=commit;h=67cccfe17d1b3da1ed6c79e643c9be95ebde9642 (commit)], add an shdlc llc module to llc core [http://git.kernel.org/linus/;a=commit;h=4a61cd6687fc6348d08724676d34e38160d6cf9b (commit)], LLCP raw socket support [http://git.kernel.org/linus/;a=commit;h=4463523bef98ff827a89cf8219db7dfac4350241 (commit)]

= Block =
 * UBI (Unsorted Block Images), targetted for flash devices: Fastmap support. Fastmap is a mechanism which allows attaching an UBI device in nearly constant time. Instead of scanning the whole MTD device it only has to locate a checkpoint (called fastmap) on the device. The on-flash fastmap contains all information needed to attach the device [http://git.kernel.org/linus/;a=commit;h=dbb7d2a88d2a7bd3624e090bee42cdee048d9290 (commit 1], [http://git.kernel.org/linus/;a=commit;h=1c865749999efdae63ddfb73b911ee04e1d4e1c8 2], [http://git.kernel.org/linus/;a=commit;h=dac6e2087a4143cfc3fc1017bf24b9d4be3055b7 3], [http://git.kernel.org/linus/;a=commit;h=5638b33abffd967dda4f984a247925b7af38b23d 4], [http://git.kernel.org/linus/;a=commit;h=8199b901a31b6e89b63842643f644fc05b403b20 5], [http://git.kernel.org/linus/;a=commit;h=00abf3041590da6ad7533bf592e8dd452820109f 6], [http://git.kernel.org/linus/;a=commit;h=a7306653705e456c8affeb4efe9542b9f6b757ad 7], [http://git.kernel.org/linus/;a=commit;h=8974b15c6e84e686201d382c7d459aa9c8c96572 8], [http://git.kernel.org/linus/;a=commit;h=76ac66e469f084d41742ba08923de76fbdc7dce3 9)]
