kernel: jbd2: add miss release buffer head in fc_do_one_pass()
A reference count leak was found in the Linux kernel's JBD2 journaling subsystem. The fcdoonepass function, used during fast commit replay, fails to release a buffer head after use. This results in a reference count leak that can prevent proper buffer memory cleanup over time...
kernel: jbd2: fix potential buffer head reference count leak
A buffer head reference count leak was found in the JBD2 journaling layer used by ext4. When jbd2fcwaitbufs encounters a non-uptodate buffer and returns -EIO, the journal offset is not updated, causing subsequent buffer release to skip some buffer heads...
