We need this because\nwe want to add common code to to all drivers in the mtd core level,\nwhich is impossible with the current interface when MTD clients\ncall driver functions like \u0027read()\u0027 or \u0027write()\u0027 directly.\n\nAt this point we just introduce a new inline wrapper function, but\nlater some of them are expected to gain more code.

In this case free won\u0027t free anything because csum_bytes\nis modified before we dro the lock in our reservation path, so free rightly\ndoesn\u0027t release any space because the reservation code may be depending on that\nreservation. However if we fail, we need the reservation side to do the free at\nthat point since that space is no longer in use. So as it stands the code was\ndoing this fine and it worked out, except in case #2\n\n2) We don\u0027t race with free. Nobody comes in and changes anything, and our\nreservation fails. In this case we didn\u0027t reserve anything anyway and we just\nneed to clean up csum_bytes but not free anything. So we keep track of\ncsum_bytes before we drop the lock and if it hasn\u0027t changed we know we can just\ndecrement csum_bytes and carry on.\n\nBecause of the case where we can race with free()\u0027s since we have to drop our\nspin_lock to do the reservation, I\u0027m going to serialize all reservations with\nthe i_mutex. We already get this for free in the heavy use paths, truncate and\nfile write all hold the i_mutex, just needed to add it to page_mkwrite and\nvarious ioctl/balance things. With this patch my space leak scripts no longer\nscream bloody murder.

This is\nbecause a bunch of people call mark_inode_dirty, which is void so we can\u0027t\nreturn ENOSPC. This needs to be fixed in a few areas\n\n1) file_update_time - this updates the mtime and such when writing to a file,\nwhich will call mark_inode_dirty. So copy file_update_time into btrfs so we can\ncall btrfs_dirty_inode directly and return an error if we get one appropriately.\n\n2) fix symlinks to use btrfs_setattr for -\u003esetattr. For some reason we weren\u0027t\nsetting -\u003esetattr for symlinks, even though we should have been. This catches\none of the cases where we were getting errors in mark_inode_dirty.\n\n3) Fix btrfs_setattr and btrfs_setsize to call btrfs_dirty_inode directly\ninstead of mark_inode_dirty. This lets us return errors properly for truncate\nand chown/anything related to setattr.\n\n4) Add a new btrfs_fs_dirty_inode which will just call btrfs_dirty_inode and\nprint an error if we have one. The only remaining user we can\u0027t control for\nthis is touch_atime(), but we don\u0027t really want to keep people from walking\ndown the tree if we don\u0027t have space to save the atime update, so just complain\nbut don\u0027t worry about it.\n\nWith this patch xfstests 83 complains a handful of times instead of hundreds of\ntimes.

We rely on get_{idle,iowait}_time functions to retrieve\nproper data.\n\nThese functions, however, use usecs_to_cputime to translate micro\nseconds time to cputime64_t. This is just an alias to usecs_to_jiffies\nwhich reduces the data type from u64 to unsigned int and also checks\nwhether the given parameter overflows jiffies_to_usecs(MAX_JIFFY_OFFSET)\nand returns MAX_JIFFY_OFFSET in that case.\n\nWhen we overflow depends on CONFIG_HZ but especially for CONFIG_HZ_300\nit is quite low (1431649781) so we are getting MAX_JIFFY_OFFSET for\n\u003e3000s! until we overflow unsigned int. Just for reference\nCONFIG_HZ_100 has an overflow window around 20s, CONFIG_HZ_250 ~8s and\nCONFIG_HZ_1000 ~2s.\n\nThis results in a bug when people saw [h]top going mad reporting 100%\nCPU usage even though there was basically no CPU load. The reason was\nsimply that /proc/stat stopped reporting idle/io_wait changes (and\nreported MAX_JIFFY_OFFSET) and so the only change happening was for user\nsystem time.\n\nLet\u0027s use nsecs_to_jiffies64 instead which doesn\u0027t reduce the precision\nto 32b type and it is much more appropriate for cumulative time values\n(unlike usecs_to_jiffies which intended for timeout calculations).\n\nSigned-off-by: Michal Hocko \u003cmhocko@suse.cz\u003e\nTested-by: Artem S.

The root cause is that when __d_path() misses the root\nit had been told to look for, it stores the location of the most remote ancestor\nin *root. Without grabbing references. Sure, at the moment of call it had\nbeen pinned down by what we have in *path. And if we raced with umount -l, we\ncould have very well stopped at vfsmount/dentry that got freed as soon as\nprepend_path() dropped vfsmount_lock.\n\nIt is safe to compare these pointers with pre-existing (and known to be still\nalive) vfsmount and dentry, as long as all we are asking is \"is it the same\naddress?\". Dereferencing is not safe and apparmor ended up stepping into\nthat. d_namespace_path() really wants to examine the place where we stopped,\neven if it\u0027s not connected to our namespace. As the result, it looked\nat -\u003ed_sb-\u003es_magic of a dentry that might\u0027ve been already freed by that point.\nAll other callers had been careful enough to avoid that, but it\u0027s really\na bad interface - it invites that kind of trouble.\n\nThe fix is fairly straightforward, even though it\u0027s bigger than I\u0027d like:\n\t* prepend_path() root argument becomes const.\n\t* __d_path() is never called with NULL/NULL root. It was a kludge\nto start with. Instead, we have an explicit function - d_absolute_root().\nSame as __d_path(), except that it doesn\u0027t get root passed and stops where\nit stops. apparmor and tomoyo are using it.\n\t* __d_path() returns NULL on path outside of root. The main\ncaller is show_mountinfo() and that\u0027s precisely what we pass root for - to\nskip those outside chroot jail. Those who don\u0027t want that can (and do)\nuse d_path().\n\t* __d_path() root argument becomes const. Everyone agrees, I hope.\n\t* apparmor does *NOT* try to use __d_path() or any of its variants\nwhen it sees that path-\u003emnt is an internal vfsmount. In that case it\u0027s\ndefinitely not mounted anywhere and dentry_path() is exactly what we want\nthere. Handling of sysctl()-triggered weirdness is moved to that place.\n\t* if apparmor is asked to do pathname relative to chroot jail\nand __d_path() tells it we it\u0027s not in that jail, the sucker just calls\nd_absolute_path() instead. That\u0027s the other remaining caller of __d_path(),\nBTW.\n * seq_path_root() does _NOT_ return -ENAMETOOLONG (it\u0027s stupid anyway -\nthe normal seq_file logics will take care of growing the buffer and redoing\nthe call of -\u003eshow() just fine). However, if it gets path not reachable\nfrom root, it returns SEQ_SKIP.
