Along with the\nloss of characters, this also fixes the associated loss of sync between\ntty output and the ldisc state when characters cannot be immediately\nwritten to the tty driver.\n\nThe echo buffer stores (in addition to characters) state operations that need\nto be done at the time of character output (like management of the column\nposition). This allows echo to cooperate correctly with program output,\nsince the ldisc state remains consistent with actual characters written.\n\nSince the echo buffer code now isolates the tty column state code\nto the process_out* and process_echoes functions, we can remove the\nBig Kernel Lock (BKL) and replace it with mutex locks.\n\nHighlights are:\n\n* Handles echo (and other ldisc output) when tty driver buffer is full\n - continuous program output can block echo\n* Saves echo when tty is in stopped state (e.g. ^S)\n - (e.g.: ^Q will correctly cause held characters to be released for output)\n* Control character pairs (e.g. \"^C\") are treated atomically and not\n split up by interleaved program output\n* Line discipline state is kept consistent with characters sent to\n the tty driver\n* Remove the big kernel lock (BKL) from N_TTY line discipline\n\nSigned-off-by: Joe Peterson \u003cjoe@skyrush.com\u003e\nSigned-off-by: Alan Cox \u003calan@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e482a2378f3d1aef7fa8942f8f163078f01bb456", "tree": "e1bb3020b41b9d4bb919a587d93370ca808b3e29", "parents": [ "68a784cb1add52543644a879ef601f3b52d18623" ], "author": { "name": "Sonic Zhang", "email": "sonic.zhang@analog.com", "time": "Fri Jan 02 13:40:45 2009 +0000" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jan 02 10:19:35 2009 -0800" }, "message": "Blackfin Serial Driver: Remove BI status for known_good_char\n\nSigned-off-by: Sonic Zhang \u003csonic.zhang@analog.com\u003e\nSigned-off-by: Bryan Wu \u003ccooloney@kernel.org\u003e\nSigned-off-by: Alan Cox \u003calan@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "68a784cb1add52543644a879ef601f3b52d18623", "tree": "88f4cd4a729a48edace500c8d164f4c01c443712", "parents": [ "b6efa1eabbe8d23fd7dcad1eed8ce945f4adea83" ], "author": { "name": "Sonic Zhang", "email": "sonic.zhang@analog.com", "time": "Fri Jan 02 13:40:38 2009 +0000" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jan 02 10:19:34 2009 -0800" }, "message": "Blackfin Serial Driver: Fix bug - BF527-EZKIT unable to receive large files over UART in DMA mode\n\nAdd spin_lock_irqsave() when receive and transfer data.\n\nSigned-off-by: Sonic Zhang \u003csonic.zhang@analog.com\u003e\nSigned-off-by: Bryan Wu \u003ccooloney@kernel.org\u003e\nSigned-off-by: Alan Cox \u003calan@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b6efa1eabbe8d23fd7dcad1eed8ce945f4adea83", "tree": "b2e6ee03edfdcc06b164a38476ab04d7a5b24f34", "parents": [ "80d5c474b87da88eca8e1ab034e26daa9f688130" ], "author": { "name": "Sonic Zhang", "email": "sonic.zhang@analog.com", "time": "Fri Jan 02 13:40:31 2009 +0000" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jan 02 10:19:34 2009 -0800" }, "message": "Blackfin Serial Driver: Clean serial console and early prink code.\n\nSigned-off-by: Sonic Zhang \u003csonic.zhang@analog.com\u003e\nSigned-off-by: Bryan Wu \u003ccooloney@kernel.org\u003e\nSigned-off-by: Alan Cox \u003calan@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "80d5c474b87da88eca8e1ab034e26daa9f688130", "tree": "adb114b756b95541cefaba89cff38180a074003b", "parents": [ "52e15f0eae193a8e4ca31c1520179b8d65c79811" ], "author": { "name": "Graf Yang", "email": "graf.yang@analog.com", "time": "Fri Jan 02 13:40:22 2009 +0000" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jan 02 10:19:34 2009 -0800" }, "message": "Blackfin Serial Driver: fix bug - SIR driver stop receiving randomly\n\nBug description:\nThe IRDA receiver may can\u0027t receiving any more after processed some signals.\n\nTo duplicate this issue is put three IRDA devices together, one blackfin,\ntwo none blackfin, they will detect each other.

So it\u0027s\nsad to see it going neglected.\n\nWith CONFIG_PROFILING turned on (which is probably the common case at least\nfor distros and kernel developers), sizeof(struct dcache) \u003d\u003d 208 here\n(64-bit). This gives 19 objects per slab.\n\nI packed d_mounted into a hole, and took another 4 bytes off the inline\nname length to take the padding out from the end of the structure. This\nshinks it to 200 bytes. I could have gone the other way and increased the\nlength to 40, but I\u0027m aiming for a magic number, read on...\n\nI then got rid of the d_cookie pointer. This shrinks it to 192 bytes. Rant:\nwhy was this ever a good idea? The cookie system should increase its hash\nsize or use a tree or something if lookups are a problem. Also the \"fast\ndcookie lookups\" in oprofile should be moved into the dcookie code -- how\ncan oprofile possibly care about the dcookie_mutex? It gets dropped after\nget_dcookie() returns so it can\u0027t be providing any sort of protection.\n\nAt 192 bytes, 21 objects fit into a 4K page, saving about 3MB on my system\nwith ~140 000 entries allocated. 192 is also a multiple of 64, so we get\nnice cacheline alignment on 64 and 32 byte line systems -- any given dentry\nwill now require 3 cachelines to touch all fields wheras previously it\nwould require 4.\n\nI know the inline name size was chosen quite carefully, however with the\nreduction in cacheline footprint, it should actually be just about as fast\nto do a name lookup for a 36 character name as it was before the patch (and\nfaster for other sizes). The memory footprint savings for names which are\n\u003c\u003d 32 or \u003e 36 bytes long should more than make up for the memory cost for\n33-36 byte names.\n\nPerformance is a feature...\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "e2b689d82c0394e5239a3557a217f19e2f47f1be", "tree": "5184413c8c872f84ef002f183db70a47b081a8dd", "parents": [ "be6d3e56a6b9b3a4ee44a0685e39e595073c6f0d" ], "author": { "name": "Richard Kennedy", "email": "richard@rsk.demon.co.uk", "time": "Thu Dec 04 11:17:47 2008 +0000" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Dec 31 18:07:37 2008 -0500" }, "message": "fs: reorder struct inotify_device on 64bits to remove padding\n\nReorder struct inotify_device to remove 8 bytes of padding on 64bit\nbuilds, reducing size to 128 bytes .
