fs: Mark function as static in ext3/dir.c

2014-03-03T10:30:59Z

Mark function as static in ext3/dir.c because it is not used outside this file. This also eliminates the following warning in ext3/dir.c: fs/ext3/dir.c:278:8: warning: no previous prototype for ‘ext3_dir_llseek’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria Reviewed-by: Josh Triplett Signed-off-by: Jan Kara

[readdir] convert ext3

2013-06-29T08:46:49Z

new helper: dir_relax(inode). Call when you are in location that will _not_ be invalidated by directory modifications (block boundary, in case of ext*). Returns whether the directory has survived (dropping i_mutex allows rmdir to kill the sucker; if it returns false to us, ->iterate() is obviously done) Signed-off-by: Al Viro

ext3: pass custom EOF to generic_file_llseek_size()

2012-07-22T20:00:30Z

Use the new custom EOF argument to generic_file_llseek_size so that SEEK_END will go to the max hash value for htree dirs in ext3 rather than to i_size_read() Signed-off-by: Eric Sandeen Signed-off-by: Al Viro

vfs: allow custom EOF in generic_file_llseek code

2012-07-22T20:00:15Z

For ext3/4 htree directories, using the vfs llseek function with SEEK_END goes to i_size like for any other file, but in reality we want the maximum possible hash value. Recent changes in ext4 have cut & pasted generic_file_llseek() back into fs/ext4/dir.c, but replicating this core code seems like a bad idea, especially since the copy has already diverged from the vfs. This patch updates generic_file_llseek_size to accept both a custom maximum offset, and a custom EOF position. With this in place, ext4_dir_llseek can pass in the appropriate maximum hash position for both maxsize and eof, and get what it wants. As far as I know, this does not fix any bugs - nfs in the kernel doesn't use SEEK_END, and I don't know of any user who does. But some ext4 folks seem keen on doing the right thing here, and I can't really argue. (Patch also fixes up some comments slightly) Signed-off-by: Eric Sandeen Signed-off-by: Al Viro

ext3: return 32/64-bit dir name hash according to usage type

2012-05-15T21:34:39Z

This is based on commit d1f5273e9adb40724a85272f248f210dc4ce919a ext4: return 32/64-bit dir name hash according to usage type by Fan Yong Traditionally ext2/3/4 has returned a 32-bit hash value from llseek() to appease NFSv2, which can only handle a 32-bit cookie for seekdir() and telldir(). However, this causes problems if there are 32-bit hash collisions, since the NFSv2 server can get stuck resending the same entries from the directory repeatedly. Allow ext3 to return a full 64-bit hash (both major and minor) for telldir to decrease the chance of hash collisions. This patch does implement a new ext3_dir_llseek op, because with 64-bit hashes, nfs will attempt to seek to a hash "offset" which is much larger than ext3's s_maxbytes. So for dx dirs, we call generic_file_llseek_size() with the appropriate max hash value as the maximum seekable size. Otherwise we just pass through to generic_file_llseek().
