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.

combination of a patch by myself and Peter\nStaubach.\n\nTrond: If we allow other processes to dirty pages while a process is doing\na consistency sync to disk, we can end up never making progress.\n\nPeter: Attached is a patch which addresses a continuing problem with\nthe NFS client generating out of order WRITE requests. While\nthis is compliant with all of the current protocol\nspecifications, there are servers in the market which can not\nhandle out of order WRITE requests very well. Also, this may\nlead to sub-optimal block allocations in the underlying file\nsystem on the server. This may cause the read throughputs to\nbe reduced when reading the file from the server.\n\nPeter: There has been a lot of work recently done to address out of\norder issues on a systemic level. However, the NFS client is\nstill susceptible to the problem. Out of order WRITE\nrequests can occur when pdflush is in the middle of writing\nout pages while the process dirtying the pages calls\ngeneric_file_buffered_write which calls\ngeneric_perform_write which calls\nbalance_dirty_pages_rate_limited which ends up calling\nwriteback_inodes which ends up calling back into the NFS\nclient to writes out dirty pages for the same file that\npdflush happens to be working with.\n\nSigned-off-by: Peter Staubach \u003cstaubach@redhat.com\u003e\n[modification by Trond to merge the two similar patches]\nSigned-off-by: Trond Myklebust
