Adrian Hunter	6dcfac4f13	UBIFS: TNC / GC race fixes ... - update GC sequence number if any nodes may have been moved even if GC did not finish the LEB - don't ignore error return when reading Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>	2008-09-17 14:23:26 +03:00
Adrian Hunter	601c0bc467	UBIFS: allow for racing between GC and TNC ... The TNC mutex is unlocked prematurely when reading leaf nodes with non-hashed keys. This is unsafe because the node may be moved by garbage collection and the eraseblock unmapped, although that has never actually happened during stress testing. This patch fixes the flaw by detecting the race and retrying with the TNC mutex locked. Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com>	2008-08-25 14:34:02 +03:00
