      "message": "fsnotify: unified filesystem notification backend\n\nfsnotify is a backend for filesystem notification.  fsnotify does\nnot provide any userspace interface but does provide the basis\nneeded for other notification schemes such as dnotify.  fsnotify\ncan be extended to be the backend for inotify or the upcoming\nfanotify.  fsnotify provides a mechanism for \"groups\" to register for\nsome set of filesystem events and to then deliver those events to\nthose groups for processing.\n\nfsnotify has a number of benefits, the first being actually shrinking the size\nof an inode.  Before fsnotify to support both dnotify and inotify an inode had\n\n        unsigned long           i_dnotify_mask; /* Directory notify events */\n        struct dnotify_struct   *i_dnotify; /* for directory notifications */\n        struct list_head        inotify_watches; /* watches on this inode */\n        struct mutex            inotify_mutex;  /* protects the watches list\n\nBut with fsnotify this same functionallity (and more) is done with just\n\n        __u32                   i_fsnotify_mask; /* all events for this inode */\n        struct hlist_head       i_fsnotify_mark_entries; /* marks on this inode */\n\nThat\u0027s right, inotify, dnotify, and fanotify all in 64 bits.  We used that\nmuch space just in inotify_watches alone, before this patch set.\n\nfsnotify object lifetime and locking is MUCH better than what we have today.\ninotify locking is incredibly complex.  See 8f7b0ba1c8539 as an example of\nwhat\u0027s been busted since inception.  inotify needs to know internal semantics\nof superblock destruction and unmounting to function.  The inode pinning and\nvfs contortions are horrible.\n\nno fsnotify implementers do allocation under locks.  This means things like\nf04b30de3 which (due to an overabundance of caution) changes GFP_KERNEL to\nGFP_NOFS can be reverted.  There are no longer any allocation rules when using\nor implementing your own fsnotify listener.\n\nfsnotify paves the way for fanotify.  In brief fanotify is a notification\nmechanism that delivers the lisener both an \u0027event\u0027 and an open file descriptor\nto the object in question.  This means that fanotify is pathname agnostic.\nSome on lkml may not care for the original companies or users that pushed for\nTALPA, but fanotify was designed with flexibility and input for other users in\nmind.  The readahead group expressed interest in fanotify as it could be used\nto profile disk access on boot without breaking the audit system.  The desktop\nsearch groups have also expressed interest in fanotify as it solves a number\nof the race conditions and problems present with managing inotify when more\nthan a limited number of specific files are of interest.  fanotify can provide\nfor a userspace access control system which makes it a clean interface for AV\nvendors to hook without trying to do binary patching on the syscall table,\nLSM, and everywhere else they do their things today.  With this patch series\nfanotify can be implemented in less than 1200 lines of easy to review code.\nAlmost all of which is the socket based user interface.\n\nThis patch series builds fsnotify to the point that it can implement\ndnotify and inotify_user.  Patches exist and will be sent soon after\nacceptance to finish the in kernel inotify conversion (audit) and implement\nfanotify.\n\nSigned-off-by: Eric Paris \u003ceparis@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\n"
