https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D213507 --- Comment #19 from Damjan Jovanovic <damjan.jov@gmail.com> --- I am still doing my test. That isn't the only vfs_bio_clrbuf() in msdosfs. IMHO we really should "find all the incomplete brelse() calls". How do "incomplete brelse() calls" work? What is the general rule? Accordin= g to that UFS patch it seems to be: a buf's b_data can only be changed if you subsequently bwrite() it, or brelse() it with b_flags containing B_INVAL | B_RELBUF | B_NOCACHE and not containing B_ASYNC | B_CACHE. If bwrite() fails you must brelse() the buf with those flags instead. Is that right? --=20 You are receiving this mail because: You are the assignee for the bug.=
