It is therefore time to\nenlist the aid of lockdep.\n\nThis set of patches is inspired by earlier work by Peter\nZijlstra and Thomas Gleixner, and takes the following approach:\n\no\tSet up separate lockdep classes for RCU, RCU-bh, and RCU-sched.\n\no\tSet up separate lockdep classes for each instance of SRCU.\n\no\tCreate primitives that check for being in an RCU read-side\n\tcritical section. These return exact answers if lockdep is\n\tfully enabled, but if unsure, report being in an RCU read-side\n\tcritical section. (We want to avoid false positives!)\n\tThe primitives are:\n\n\tFor RCU: rcu_read_lock_held(void)\n\n\tFor RCU-bh: rcu_read_lock_bh_held(void)\n\n\tFor RCU-sched: rcu_read_lock_sched_held(void)\n\n\tFor SRCU: srcu_read_lock_held(struct srcu_struct *sp)\n\no\tAdd rcu_dereference_check(), which takes a second argument\n\tin which one places a boolean expression based on the above\n\tprimitives and/or lockdep_is_held().\n\no\tA new kernel configuration parameter, CONFIG_PROVE_RCU, enables\n\trcu_dereference_check(). This depends on CONFIG_PROVE_LOCKING,\n\tand should be quite helpful during the transition period while\n\tCONFIG_PROVE_RCU-unaware patches are in flight.\n\nThe existing rcu_dereference() primitive does no checking, but\nupcoming patches will change that.\n\nSigned-off-by: Paul E.

However, going up 1 level wouldn\u0027t give any more empty slot so\nit takes C and when the whole thing restarts nobody notices the high bit\nset beyond the top level.\n\nThis patch fixes the bug by changing the fail exit condition check to full\nid limit check.\n\nBased-on-patch-from: Eric Paris \u003ceparis@redhat.com\u003e\nReported-by: Eric Paris \u003ceparis@redhat.com\u003e\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "9d3f1881abeae0494a27716b08fcf2d3264bb0fa", "tree": "f457dd2d35af29bc831b93865efa47229d0b9bee", "parents": [ "b6c58b1d987a5795086c5c2babd8c7367d2fdb8c", "bc10e875d4aeaa93a0d418d8b4346b72f5067ea0" ], "author": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Tue Feb 02 11:33:45 2010 +0900" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Tue Feb 02 11:33:45 2010 +0900" }, "message": "Merge branch \u0027sh/stable-updates\u0027\n" }, { "commit": "660e2acad81c19b404f7d7d06e57a6d5e6ce7426", "tree": "377b2e0f9d4219b301c1f3c16311a7710e2d4abc", "parents": [ "08b36c4a02b5a9db609fc6d93b9c41d7fa75713c" ], "author": { "name": "Chris Smith", "email": "chris.smith@st.com", "time": "Wed Jan 27 22:03:11 2010 +0900" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Wed Jan 27 22:03:11 2010 +0900" }, "message": "sh: kmemleak support.\n\nEnables support for kmemleak on sh.\n\nSigned-off-by: Chris Smith \u003cchris.smith@st.com\u003e\nSigned-off-by: Paul Mundt \u003clethal@linux-sh.org\u003e\n" }, { "commit": "51c24aaacaea90c8e87f1dec75a2ac7622b593f8", "tree": "9f54936c87764bef75e97395cb56b7d1e0df24c6", "parents": [ "4276e47e2d1c85a2477caf0d22b91c4f2377fba8", "6be325719b3e54624397e413efd4b33a997e55a3" ], "author": { "name": "David S.

The only reason I\n: can think of ever using gzip would be if you needed the additional\n: compression (eg, because you have limited flash to store the image.)\n:\n: I would argue that the default for ARM should therefore be LZO.\n\nThis patch:\n\nThe lzo compressor is worse than gzip at compression, but faster at\nextraction. Here are some figures for an ARM board I\u0027m working on:\n\nUncompressed size: 3.24Mo\ngzip 1.61Mo 0.72s\nlzo 1.75Mo 0.48s\n\nSo for a compression ratio that is still relatively close to gzip, it\u0027s\nmuch faster to extract, at least in that case.\n\nThis part contains:\n - Makefile routine to support lzo compression\n - Fixes to the existing lzo compressor so that it can be used in\n compressed kernels\n - wrapper around the existing lzo1x_decompress, as it only extracts one\n block at a time, while we need to extract a whole file here\n - config dialog for kernel compression\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: cleanup]\nSigned-off-by: Albin Tonnerre \u003calbin.tonnerre@free-electrons.com\u003e\nTested-by: Wu Zhangjin \u003cwuzhangjin@gmail.com\u003e\nAcked-by: \"H.
