From 2b3ffd7eb7b4392e3657c5046b055ca9f1f7cf5e Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 23 Aug 2011 08:28:12 +0000 Subject: xfs: wait for I/O completion when writing out pages in xfs_setattr_size The current code relies on the xfs_ioend_wait call later on to make sure all I/O actually has completed. The xfs_ioend_wait call will go away soon, so prepare for that by using the waiting filemap function.

Thus remove i_iocount, and replace the actually needed waits with calls to inode_dio_wait.

Currently it returns EIO, not negative value, when it failed. As a result, the system call returns not negative value even though an error occured. The stat(2), ls and mv commands cannot handle this error and do not work correctly. This patch fixes this bug, and returns -EIO, not EIO when an error is detected in xfs_vn_getattr().

Also use this fact to merge xfs_trans_ijoin_ref back into xfs_trans_ijoin - the third argument decides if an unlock is needed now. I'm actually starting to wonder if allowing inodes to be unlocked at transaction commit really is worth the effort. The only real benefit is that they can be unlocked earlier when commiting a synchronous transactions, but that could be solved by doing the log force manually after the unlock, too.
