The tty mutex is not\ndropped automatically when the thread sleeps like the BKL. This results\nin a blocked read or write holding the tty mutex and stalling operations\nby other devices that use the tty mutex.\n\nA review of n_hdlc read and write code shows:\n1. neither BKL or tty mutex are required for correct operation\n2. read can block while read data is available if data is posted\n between availability check and call to interruptible_sleep_on()\n3. write does not set process state to TASK_INTERRUPTIBLE\n on each pass through the processing loop which can cause\n unneeded scheduling of the thread\n\nThe unnecessary tty mutex references have been removed.\n\nRead changed to use same code as n_tty read\nfor completing reads and blocking.\n\nWrite corrected to set process state to TASK_INTERRUPTIBLE on each pass\nthrough processing loop.\n\nSigned-off-by: Paul Fulghum \u003cpaulkf@microgate.com\u003e\nAcked-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "d0694e2aeb815042aa0f3e5036728b3db4446f1d", "tree": "11e5bacd2f28df6a649dd7db707a9a697c301f9f", "parents": [ "a2a6a822adc2a91c677cb60e9bc6ffe26fa90e9f" ], "author": { "name": "Pavel Machek", "email": "pavel@ucw.cz", "time": "Sun Jan 09 08:38:48 2011 +0100" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Sat Jan 22 19:15:01 2011 -0800" }, "message": "serial: unbreak billionton CF card\n\nUnbreak Billionton CF bluetooth card.
