  "message": "message queues: increase range limits\n\nIncrease the range of various posix message queue limits.\n\nPosix gives the message queue user the ability to \u0027trade off\u0027 the maximum\nsize of messages with the number of possible messages that can be \u0027in\nflight\u0027.  Linux currently makes this trade off more restrictive than it\nneeds to be.\n\nIn particular, the maximum message size today can be made no smaller than\n8192.  This greatly restricts those applications that would like to have\nthe ability to post large numbers of very small messages.\n\nSo this task lowers the limit that the maximum message size can be set to,\nfrom 8192 to 128.  It also lowers the limit that the maximum #number of\nmessages in flight can be set to, from 10 to 1.\n\nWith these changes the message queue user can make better trade offs\nbetween #messages and message size, in order to get everything to fit\nwithin the setrlimit(RLIMIT_MSGQUEUE) limit for that particular user.\n\nThis patch also applies the values in\n\n\t/proc/sys/fs/mqueue/msg_max\n\t/proc/sys/fs/mqueue/msgsize_max\n\nas the defaults for the max #messages allowed and the max message size\nallowed, respectively, for those applications that do not supply these.\nPreviously, the defaults were hardwired to 10 and 8192, respectively.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Joe Korty \u003cjoe.korty@ccur.com\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Manfred Spraul \u003cmanfred@colorfullife.com\u003e\nCc: Nadia Derbey \u003cNadia.Derbey@bull.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
