From: Pawel Osciak Date: Wed, 28 Apr 2010 07:05:21 +0000 (-0300) Subject: V4L/DVB: Add a new ERROR flag for DQBUF after recoverable streaming errors X-Git-Tag: v2.6.35-rc1~480^2~70 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bc0f7f19ab9ba5c7ec648b400d1360b525fa1a3a;p=pandora-kernel.git V4L/DVB: Add a new ERROR flag for DQBUF after recoverable streaming errors This flag is intended to indicate streaming errors, which might have resulted in corrupted video data in the buffer, but the buffer can still be reused and streaming may continue. Setting this flag and returning 0 is different from returning EIO. The latter should now indicate more serious (unrecoverable) errors. This patch also solves a problem with the ioctl handling code in vl42-ioctl.c, which does not copy buffer identification data back to the userspace when EIO is returned, so there is no way for applications to discover on which buffer the operation failed in such cases.
