Subject: [PATCH] ext3: ext3_symlink should use GFP_NOFS allocations inside
X-Git-Tag: v2.6.16-rc6~25
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0adb25d2e71ab047423d6fc63d5d184590d0a66f;p=pandora-kernel.git

[PATCH] ext3: ext3_symlink should use GFP_NOFS allocations inside

This patch fixes illegal __GFP_FS allocation inside ext3 transaction in
ext3_symlink().  Such allocation may re-enter ext3 code from
try_to_free_pages.  But JBD/ext3 code keeps a pointer to current journal
handle in task_struct and, hence, is not reentrable.

This bug led to "Assertion failure in journal_dirty_metadata()" messages.
