reiserfs: use monotonic time for j_trans_start_time

2018-08-22T17:52:50Z

Using CLOCK_REALTIME time_t timestamps breaks on 32-bit systems in 2038, and gives surprising results with a concurrent settimeofday(). This changes the reiserfs journal timestamps to use ktime_get_seconds() instead, which makes it use a 64-bit CLOCK_MONOTONIC stamp. In the procfs output, the monotonic timestamp needs to be converted back to CLOCK_REALTIME to keep the existing ABI.

proc: introduce proc_create_single{,_data}

2018-05-16T05:23:35Z

Variants of proc_create{,_data} that directly take a seq_file show callback and drastically reduces the boilerplate code in the callers. All trivial callers converted over. Signed-off-by: Christoph Hellwig

reiserfs: fix deadlock in umount

2013-08-05T13:37:37Z

Since remove_proc_entry() started to wait for IO in progress (i.e. since 2007 or so), the locking in fs/reiserfs/proc.c became wrong; if procfs read happens between the moment when umount() locks the victim superblock and removal of /proc/fs/reiserfs//*, we'll get a deadlock - read will wait for s_umount (in sget(), called by r_start()), while umount will wait in remove_proc_entry() for that read to finish, holding s_umount all along. Fortunately, the same change allows a much simpler race avoidance - all we need to do is remove the procfs entries in the very beginning of reiserfs ->kill_sb(); that'll guarantee that pointer to superblock will remain valid for the duration for procfs IO, so we don't need sget() to keep the sucker alive. As the matter of fact, we can get rid of the home-grown iterator completely, and use single_open() instead. Signed-off-by: Al Viro

reiserfs: Don't access the proc_dir_entry in r_open(), r_start() r_show()

2013-05-01T21:29:43Z

Don't access the proc_dir_entry in ReiserFS's r_open(), r_start() r_show() procfs interface functions. ReiserFS stores the ->show() method pointer in PDE->data and the super_block pointer in PDE->parent->data. This isn't changing. Currently, ReiserFS passes the PDE pointer into seq_file::private from r_open() so that r_start() and r_show() can then access it. Instead, use seq_open_private() to allocate a two-pointer struct that's passed through seq_file::private and put the ->show() method and the sb pointers in there.

proc: Add proc_mkdir_data()

2013-05-01T21:29:41Z

Add proc_mkdir_data() to allow procfs directories to be created that are annotated at the time of creation with private data rather than doing this post-creation. This means no access is then required to the proc_dir_entry struct to set this.
