Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "6631424fd2efd75e7394b318ad2a8597327857a9", "tree": "09cc31036c9c53c5faec578ad68d443fd53e1b3d", "parents": [ "c45140a996b511bccdcbbdbea7e36f001826bdf2", "c0cd884af045338476b8e69a61fceb3f34ff22f1" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 29 14:41:18 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 29 14:41:18 2010 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (33 commits)\n r8169: offical fix for CVE-2009-4537 (overlength frame DMAs)\n ipv6: Don\u0027t drop cache route entry unless timer actually expired.\n tulip: Add missing parens.\n r8169: fix broken register writes\n pcnet_cs: add new id\n bonding: fix broken multicast with round-robin mode\n drivers/net: Fix continuation lines\n e1000: do not modify tx_queue_len on link speed change\n net: ipmr/ip6mr: prevent out-of-bounds vif_table access\n ixgbe: Do not run all Diagnostic offline tests when VFs are active\n igb: use correct bits to identify if managability is enabled\n benet: Fix compile warnnings in drivers/net/benet/be_ethtool.c\n net: Add MSG_WAITFORONE flag to recvmmsg\n e1000e: do not modify tx_queue_len on link speed change\n igbvf: do not modify tx_queue_len on link speed change\n ipv4: Restart rt_intern_hash after emergency rebuild (v2)\n ipv4: Cleanup struct net dereference in rt_intern_hash\n net: fix netlink address dumping in IPv4/IPv6\n tulip: Fix null dereference in uli526x_rx_packet()\n gianfar: fix undo of reserve()\n ...\n" }, { "commit": "de329820e920cd9cfbc2127cad26a37026260cce", "tree": "c392dbee75854e1f0b950f9d16dcf03214c63e80", "parents": [ "ad4ba059005f18ec9e274966c16d99fc5ce8b2cd" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 29 14:30:19 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 29 14:30:19 2010 -0700" }, "message": "ext3: fix broken handling of EXT3_STATE_NEW\n\nIn commit 9df93939b735 (\"ext3: Use bitops to read/modify\nEXT3_I(inode)-\u003ei_state\") ext3 changed its internal \u0027i_state\u0027 variable to\nuse bitops for its state handling.

Currently we test the cgroup freezer\nstate of the resuming tasks to see if the cgroup is FROZEN. If so\nthen we don\u0027t thaw the task. However, the FREEZING state also indicates\nthat the task should remain frozen.\n\nThis also avoids a problem pointed out by Oren Ladaan: the freezer state\ntransition from FREEZING to FROZEN is updated lazily when userspace reads\nor writes the freezer.state file in the cgroup filesystem. This means that\nresume will thaw tasks in cgroups which should be in the FROZEN state if\nthere is no read/write of the freezer.state file to trigger this\ntransition before suspend.\n\nNOTE: Another \"simple\" solution would be to always update the cgroup\nfreezer state during resume. However it\u0027s a bad choice for several reasons:\nUpdating the cgroup freezer state is somewhat expensive because it requires\nwalking all the tasks in the cgroup and checking if they are each frozen.\nWorse, this could easily make resume run in N^2 time where N is the number\nof tasks in the cgroup. Finally, updating the freezer state from this code\npath requires trickier locking because of the way locks must be ordered.\n\nInstead of updating the freezer state we rely on the fact that lazy\nupdates only manage the transition from FREEZING to FROZEN. We know that\na cgroup with the FREEZING state may actually be FROZEN so test for that\nstate too. This makes sense in the resume path even for partially-frozen\ncgroups -- those that really are FREEZING but not FROZEN.\n\nReported-by: Oren Ladaan \u003corenl@cs.columbia.edu\u003e\nSigned-off-by: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nCc: stable@kernel.org\nSigned-off-by: Rafael J.
