This patch intends to actually give us real O_SYNC\nsemantics in addition to the O_DSYNC semantics. After Jan\u0027s O_SYNC\npatches which are required before this patch it\u0027s actually surprisingly\nsimple, we just need to figure out when to set the datasync flag to\nvfs_fsync_range and when not.\n\nThis patch renames the existing O_SYNC flag to O_DSYNC while keeping it\u0027s\nnumerical value to keep binary compatibility, and adds a new real O_SYNC\nflag. To guarantee backwards compatiblity it is defined as expanding to\nboth the O_DSYNC and the new additional binary flag (__O_SYNC) to make\nsure we are backwards-compatible when compiled against the new headers.\n\nThis also means that all places that don\u0027t care about the differences can\njust check O_DSYNC and get the right behaviour for O_SYNC, too - only\nplaces that actuall care need to check __O_SYNC in addition. Drivers and\nnetwork filesystems have been updated in a fail safe way to always do the\nfull sync magic if O_DSYNC is set. The few places setting O_SYNC for\nlower layers are kept that way for now to stay failsafe.\n\nWe enforce that O_DSYNC is set when __O_SYNC is set early in the open path\nto make sure we always get these sane options.\n\nNote that parisc really screwed up their headers as they already define a\nO_DSYNC that has always been a no-op. We try to repair it by using it for\nthe new O_DSYNC and redefinining O_SYNC to send both the traditional\nO_SYNC numerical value _and_ the O_DSYNC one.\n\nCc: Richard Henderson \u003crth@twiddle.net\u003e\nCc: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nCc: Grant Grundler \u003cgrundler@parisc-linux.org\u003e\nCc: \"David S.
