So we currently have a small window where\nthe reference count on a network namespace may be incremented when opening\na /proc file when it has already gone to zero.\n\nTo fix this introduce maybe_get_net and get_proc_net.\n\nmaybe_get_net increments the network namespace reference count only if it is\ngreater then zero, ensuring we don\u0027t increment a reference count after it\nhas gone to zero.\n\nget_proc_net handles all of the magic to go from a proc inode to the network\nnamespace instance and call maybe_get_net on it.\n\nPROC_NET the old accessor is removed so that we don\u0027t get confused and use\nthe wrong helper function.\n\nThen I fix up the callers to use get_proc_net and handle the case case\nwhere get_proc_net returns NULL.

It\nreverts parts of commit b27f03d4bdc145a09fb7b0c0e004b29f1ee555fa by\nconverting fs/proc/array.c back to cputime_t. The new functions\ntask_utime and task_stime now return cputime_t instead of clock_t. If\nCONFIG_VIRT_CPU_ACCOUTING is set, task-\u003eutime and task-\u003estime are\nreturned directly instead of using sum_exec_runtime.\n\nPatch is tested on s390x with and without VIRT_CPU_ACCOUTING as well as\non i386.\n\n[ mingo@elte.hu: cleanups, comments. ]\n\nSigned-off-by: Christian Borntraeger \u003cborntraeger@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "5ea473a1dfeca2ee38c5dd458c1174d129e6b64e", "tree": "7ed66c900149f452ebeda379ce3264da9515b9dd", "parents": [ "ff8e210a9550ad760a62e9803938cd04f9fb0851" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@sw.ru", "time": "Tue Jul 31 00:38:50 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Jul 31 15:39:40 2007 -0700" }, "message": "Fix leaks on /proc/{*/sched,sched_debug,timer_list,timer_stats}\n\nOn every open/close one struct seq_operations leaks.\nKudos to /proc/slab_allocators.\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@sw.ru\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\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": "778f3dd5a13c9e1642e0b2efea4b769387a70afa", "tree": "7a137adb91dcadf3e7b6756869ab73683ee41268", "parents": [ "040b3a2df2dd26c3e401823f3b0ce3fe99e966c5" ], "author": { "name": "David Miller", "email": "davem@davemloft.net", "time": "Fri Jul 27 22:58:37 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Sat Jul 28 19:42:22 2007 -0700" }, "message": "Fix procfs compat_ioctl regression\n\nIt is important to only provide the compat_ioctl method\nif the downstream de-\u003eproc_fops does too, otherwise this\nutterly confuses the logic in fs/compat_ioctl.c and we\nend up doing the wrong thing.\n\nSigned-off-by: David S.

But it has the nice virtue that the assiation with a session only\nlasts until the session leader exits. Which means that no reference counting\nis required. So using struct pid winds up being a simple optimization to\navoid hash table lookups.\n\nIn the long term the use of pid_nr also ensures that when we have multiple pid\nspaces mixed everything will work correctly.\n\nSigned-off-by: Eric W.
