Subject: [merged] fs-pipec-skip-file_update_time-on-frozen-fs.patch removed from -mm tree To: dmonakhov@xxxxxxxxxx,jack@xxxxxxx,viro@xxxxxxxxxxxxxxxxxx,mm-commits@xxxxxxxxxxxxxxx From: akpm@xxxxxxxxxxxxxxxxxxxx Date: Fri, 24 Jan 2014 11:03:06 -0800 The patch titled Subject: fs/pipe.c: skip file_update_time on frozen fs has been removed from the -mm tree. Its filename was fs-pipec-skip-file_update_time-on-frozen-fs.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Dmitry Monakhov <dmonakhov@xxxxxxxxxx> Subject: fs/pipe.c: skip file_update_time on frozen fs Pipe has no data associated with fs so it is not good idea to block pipe_write() if FS is frozen, but we can not update file's time on such filesystem. Let's use same idea as we use in touch_time().
