f2fs: cover free_nid management with spin_lock (2013-05-08 13:22:05 +0900)
----------------------------------------------------------------
f2fs updates for v3.10
This patch-set includes the following major enhancement patches.
o introduce a new gloabl lock scheme
o add tracepoints on several major functions
o fix the overall cleaning process focused on victim selection
o apply the block plugging to merge IOs as much as possible
o enhance management of free nids and its list
o enhance the readahead mode for node pages
o address several cretical deadlock conditions
o reduce lock_page calls
The other minor bug fixes and enhancements are as follows.
o calculation mistakes: overflow
o bio types: READ, READA, and READ_SYNC
o fix the recovery flow, data races, and null pointer errors
