It does this by\ngrabing the CIL context lock exclusively, then dropping it before\npushing the CIL if necessary. This causes serialisation of all log\nforces and pushes regardless of whether a force is necessary or not.\nAs a result fsync heavy workloads (like dbench) can be significantly\nslower with delayed logging than without.\n\nTo avoid this penalty, copy the current sequence from the context to\nthe CIL structure when they are swapped. This allows us to do\nunlocked checks on the current sequence without having to worry\nabout dereferencing context structures that may have already been\nfreed. Hence we can remove the CIL context locking in the forcing\ncode and only call into the push code if the current context matches\nthe sequence we need to force.\n\nBy passing the sequence into the push code, we can check the\nsequence again once we have the CIL lock held exclusive and abort if\nthe sequence has already been pushed. This avoids a lock round-trip\nand unnecessary CIL pushes when we have racing push calls.\n\nThe result is that the regression in dbench performance goes away -\nthis change improves dbench performance on a ramdisk from ~2100MB/s\nto ~2500MB/s. This compares favourably to not using delayed logging\nwhich retuns ~2500MB/s for the same workload.\n\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\n" }, { "commit": "1a387d3be2b30c90f20d49a3497a8fc0693a9d18", "tree": "4c8081f6620976dbfc3ecee0e26296c0890bceba", "parents": [ "2fe33661fcd79d4c53022509f7223d526b5fa233" ], "author": { "name": "Dave Chinner", "email": "dchinner@redhat.com", "time": "Tue Aug 24 11:46:31 2010 +1000" }, "committer": { "name": "Dave Chinner", "email": "david@fromorbit.com", "time": "Tue Aug 24 11:46:31 2010 +1000" }, "message": "xfs: dummy transactions should not dirty VFS state\n\nWhen we need to cover the log, we issue dummy transactions to ensure\nthe current log tail is on disk.

These crashes are caused by\nAMD Erratum 383 and result in a fatal machine check exception. Here\u0027s\nthe scenario:\n\n1. On 32-bit, the swapper_pg_dir page table is used as the initial page\ntable for booting a secondary CPU.\n\n2. To make this work, swapper_pg_dir needs a direct mapping of physical\nmemory in it (the low mappings). By adding those low, large page (2M)\nmappings (PAE kernel), we create the necessary conditions for Erratum\n383 to occur.\n\n3. Other CPUs which do not participate in the off- and onlining game may\nuse swapper_pg_dir while the low mappings are present (when leave_mm is\ncalled). For all steps below, the CPU referred to is a CPU that is using\nswapper_pg_dir, and not the CPU which is being onlined.\n\n4. The presence of the low mappings in swapper_pg_dir can result\nin TLB entries for addresses below __PAGE_OFFSET to be established\nspeculatively. These TLB entries are marked global and large.\n\n5. When the CPU with such TLB entry switches to another page table, this\nTLB entry remains because it is global.\n\n6. The process then generates an access to an address covered by the\nabove TLB entry but there is a permission mismatch - the TLB entry\ncovers a large global page not accessible to userspace.\n\n7. Due to this permission mismatch a new 4kb, user TLB entry gets\nestablished. Further, Erratum 383 provides for a small window of time\nwhere both TLB entries are present. This results in an uncorrectable\nmachine check exception signalling a TLB multimatch which panics the\nmachine.\n\nThere are two ways to fix this issue:\n\n 1. Always do a global TLB flush when a new cr3 is loaded and the\n old page table was swapper_pg_dir. I consider this a hack hard\n to understand and with performance implications\n\n 2. Do not use swapper_pg_dir to boot secondary CPUs like 64-bit\n does.\n\nThis patch implements solution 2. It introduces a trampoline_pg_dir\nwhich has the same layout as swapper_pg_dir with low_mappings. This page\ntable is used as the initial page table of the booting CPU. Later in the\nbringup process, it switches to swapper_pg_dir and does a global TLB\nflush. This fixes the crashes in our test cases.\n\n-v2: switch to swapper_pg_dir right after entering start_secondary() so\nthat we are able to access percpu data which might not be mapped in the\ntrampoline page table.\n\nSigned-off-by: Joerg Roedel \u003cjoerg.roedel@amd.com\u003e\nLKML-Reference: \u003c20100816123833.GB28147@aftab\u003e\nSigned-off-by: Borislav Petkov \u003cborislav.petkov@amd.com\u003e\nSigned-off-by: H.

The lglock provides fast access to the per-cpu lists\nto add and remove files. It also provides a snapshot of all the per-cpu lists\n(although this is very slow).\n\nOne difficulty with this approach is that a file can be removed from the list\nby another CPU. We must track which per-cpu list the file is on with a new\nvariale in the file struct (packed into a hole on 64-bit archs). Scalability\ncould suffer if files are frequently removed from different cpu\u0027s list.\n\nHowever loads with frequent removal of files imply short interval between\nadding and removing the files, and the scheduler attempts to avoid moving\nprocesses too far away. Also, even in the case of cross-CPU removal, the\nhardware has much more opportunity to parallelise cacheline transfers with N\ncachelines than with 1.\n\nA worst-case test of 1 CPU allocating files subsequently being freed by N CPUs\ndegenerates to contending on a single lock, which is no worse than before.

So proper error handling is left as an exercise for tty hackers.\n\n[ Arguably filesystem\u0027s device inode would ideally be divorced from the\ndriver\u0027s pseudo inode when it is opened, but in practice it\u0027s not clear whether\nthat will ever be worth implementing. ]\n\nCc: linux-kernel@vger.kernel.org\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "ee2ffa0dfdd2db19705f2ba1c6a4c0bfe8122dd8", "tree": "e48400d1a33f8d2e68589ccfd61637aa64462f08", "parents": [ "b04f784e5d19ed58892833dae845738972cea260" ], "author": { "name": "Nick Piggin", "email": "npiggin@kernel.dk", "time": "Wed Aug 18 04:37:35 2010 +1000" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Aug 18 08:35:47 2010 -0400" }, "message": "fs: cleanup files_lock locking\n\nfs: cleanup files_lock locking\n\nLock tty_files with a new spinlock, tty_files_lock; provide helpers to\nmanipulate the per-sb files list; unexport the files_lock spinlock.\n\nCc: linux-kernel@vger.kernel.org\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nAcked-by: Andi Kleen \u003cak@linux.intel.com\u003e\nAcked-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "b04f784e5d19ed58892833dae845738972cea260", "tree": "6060e063b5a51461fd60630d57318778fe987148", "parents": [ "2a4419b5b2a77f3f4537c14f7ad7df95770655dd" ], "author": { "name": "Nick Piggin", "email": "npiggin@kernel.dk", "time": "Wed Aug 18 04:37:34 2010 +1000" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Aug 18 08:35:47 2010 -0400" }, "message": "fs: remove extra lookup in __lookup_hash\n\nfs: remove extra lookup in __lookup_hash\n\nOptimize lookup for create operations, where no dentry should often be\ncommon-case.
