In commit 6d0bf005,\nit is moved to another function named update_t_max_wait to\navoid a build warning. But the wrong thing is that the original\n\u0027ts\u0027 is initialized in the start of function start_this_handle\nand we can calculate t_max_wait in the right way. while with\nthis change, ts is initialized within the function and t_max_wait\ncan never be calculated right.\n\nThis patch moves the initialization of ts to the original beginning\nof start_this_handle and pass it to function update_t_max_wait so\nthat it can be calculated right and the build warning is avoided also.\n\nCc: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Tao Ma \u003cboyu.mt@taobao.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nReviewed-by: Eric Sandeen \u003csandeen@redhat.com\u003e\n" }, { "commit": "f6d2f6b327ceef5c689581529a852dc6ec3b74a6", "tree": "9ae24dbb3787f596687954322c55e73570d6ed88", "parents": [ "77f4135f2a219a2127be6cc1208c42e6175b11dd" ], "author": { "name": "Eric Gouriou", "email": "egouriou@google.com", "time": "Sun May 22 21:33:00 2011 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sun May 22 21:33:00 2011 -0400" }, "message": "ext4: fix unbalanced up_write() in ext4_ext_truncate() error path\n\next4_ext_truncate() should not invoke up_write(\u0026EXT4_I(inode)-\u003ei_data_sem)\nwhen ext4_orphan_add() returns an error, as it hasn\u0027t performed a\ndown_write() yet.
