fs: Remove ext3 filesystem driver

2015-07-23T18:59:40+00:00

The functionality of ext3 is fully supported by ext4 driver. Major distributions (SUSE, RedHat) already use ext4 driver to handle ext3 filesystems for quite some time. There is some ugliness in mm resulting from jbd cleaning buffers in a dirty page without cleaning page dirty bit and also support for buffer bouncing in the block layer when stable pages are required is there only because of jbd. So let's remove the ext3 driver. This saves us some 28k lines of duplicated code. Acked-by: Theodore Ts'o Signed-off-by: Jan Kara

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

2014-03-03T10:30:59+00:00

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

2013-06-29T08:46:49+00:00

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

lseek: the "whence" argument is called "whence"

ext3: pass custom EOF to generic_file_llseek_size()

2012-07-22T20:00:30+00:00

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

2012-07-22T20:00:15+00:00

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
